<> the first time they met, the distance traveled by the two cars was the same, and the express train only ran for a while to catch up with 80*(a+1)=120*a The result was a=2, and the express train ran for 2 hours and the slow train ran for 3 hours during the first encounter, covering a distance of 240 kilometers. The remaining distance is 720-240 = 480km, and the express train still needs to run for 480 120 = 4 hours to reach place B, and stay in place B for 20 minutes. It shows that after the first encounter, the express train departed from place B again, a total of hours.
In this hour, the slow train ran another 80* kilometers. The slow train ran a total of 344 + 240 = 584 km, and the remaining distance was 720-584 = 136 km. For 136 kilometers, the two cars are going in opposite directions.
136 (120+80) = hours So the interval between the two cars = 4 hours, 58 minutes and 48 seconds.

Fishing machine is easy to die in what way to fish.

I don't know what you mean by not being easy to die, how far it has lived? Let's talk about the primary one first: the fish you buy (take) back must be healthy, at least not floating on the surface or sinking to the bottom; The fish has white spots, ulcers and the like.
The second point: the tank where goldfish are kept must be clean. The third point:
The water quality requirement is best to leave tap water for a period of time (preferably more than a day, let the bleach in the water evaporate. )。As for why we don't use well water and river water, I will talk about it below.
Point 4: Don't put the goldfish in the tank immediately after you buy it. Fifth point:
Do not feed goldfish in the tank right away. Point 6: If you want to place aquatic and sand stones in the fish tank, be sure to disinfect the fish for a period of time after placing it.
Point 7: Before putting fish in the tank, sprinkle some salt to disinfect it. Basically, when these are done, the goldfish will be able to live.
Next, let's talk about advanced and a supplement to the above First: Why do we use tap water for water quality? That's because, first, fish are more delicate nowadays.
Unlike in the past, the fish were harvested from the sky and had strong disease resistance. Today's goldfish are weak and delicate, and their resistance to water quality and germs in the water is weak. So it is not suitable for well water.
Because the well water has not undergone a disinfection and filtration process, there are too many native microorganisms in the water, which can easily cause goldfish to get sick. Second, the well water contains too many minerals, which is not good for the growth of goldfish. Third, there are a lot of goldfish in other places now, which means that the goldfish you buy locally are shipped from other places.
And not through locally farmed goldfish. The requirements for water quality are relatively high. Do a simple little experiment and know that there is no taste in drinking tap water and tasting it carefully.
But if you drink a well water and taste it carefully, you will find that the well water has a taste, which is either sweet, salty, or bitter...The same is true of rivers and rivers. Second:
Why can't goldfish be put into the tank right away? That's because the water you are holding the fish in the tank is at a different temperature, and the fish is likely to have an irritated reaction due to the difference in water temperature, which is the old saying that you will catch a cold and die. So the correct way is to put the fish and the water containing the fish into a bag, put the bag as a whole in the fish tank, so that the water temperature is naturally the same as the water temperature in the fish tank, and then put the fish into the fish tank.
Third: Don't feed the goldfish you just got back, because if you feed it immediately, either the fish will not eat and cause the water pollution of the fish tank and the lack of oxygen will die, or the fish will eat it, but it will die because it is not adapted to the environment. Fourth:
It is necessary to always pay attention to the reaction of the fish in the fish tank, for example, the fish often put their heads out of the water, which is also known as floating heads, which means that the fish tank is hypoxic, which will cause the goldfish to die of hypoxia or cause other diseases due to lack of oxygen. If the back of the fish often floats on the surface of the water, it means that the fish has rotten belly, and the internal organs decay and produce gases and die. If the fish often sinks to the bottom, there is a problem with the swim bladder.
You won't drown, but you'll be able to die easily. Then there is gill rot, which basically does not happen and can be skipped. The most common are white spot disease, powdering, and white spot disease is present in fish.

The main cause of fish death when selling fish is chlorine in the water, which kills the fish.
1. You can go to the fish market that sells tropical fish to buy a drug like "chlorine", scatter it in the water to be released according to the proportion, stir it, and wait for the chlorine gas to run out, and then release the fish. If you are stuck in the water, you should put the fish water in the tank for more than a week, so that you don't need to put medicine, but it will take a long time.
2. Water oxygenation: The water tank should be equipped with an oxygen machine and water filtration.
3. Don't feed: Never feed.
4. Remove excrement in time: keep the water in the tank clean.
5. The density of the fish must be appropriate, and do not put too many fish in the tank.
-
It is to let the fish live in the water, the water temperature should not be too high or too cold, and keep the water clean, there is a large fish pond can use an aerator or stir the fish pond to let the water in the fish pond contact with the air, keep the water microbial community stable, and the life of the fish should be longer.
-
If you want the fish to die easily, you can add some oxygen to the fish pot and feed some fish food from time to time.
-
The fish died because of the lack of oxygen, and the chlorine in the water killed it. In order to keep the fish from dying, it is necessary to increase the oxygen pump to reduce the water pressure.
-
The fish seller wants to make it difficult for the fish to die, of course. Give him a constant supply of oxygen!
-
Aerator aeration and frequent water change.

Hello dear! Fish sellers can do it in the following ways to make it difficult for fish to die1Prepare enough fresh spare water, keep the fish in large pots, use an oxygen pump to add oxygen to the water, and clean up the scales or excrement in the water every once in a while2

The speed at which the fish is killed is an important factor affecting the quality of the meat. In the process of killing fish (struggling to death), the fish will produce a lot of metabolites that the human body does not need in response to the stress response, and the faster the fish is killed, the weaker the stress response. Therefore, it is best to kill the fish immediately, use a knife or scissors to quickly cut the common carotid artery (the base of the gills), release the blood and let the fish die happily, which can reduce the production of unnecessary metabolites, and remove the fishy smell in the blood ruler to divide it quickly, rather than "suffocating" the fish to death.
In addition, the quality of the fish also depends on the vitality and health of the fish, the better the breeding environment, the stronger the vitality of the fish, after killing, the cleaner the blood, the more delicious it will be eaten. Like pork, fish has a similar "detoxification period", which means that the fish will be more delicious after a period of time, usually about 2 hours (10 times).
Oxygen is supplied with an air pump, and the fish does not die in the presence of oxygen. After selling the remaining live fish, oxygen will continue to be supplied after the water is changed. If you want the fish not to die, you must have a pump that matches the fish tank, and you need to change the water regularly, about once every two or three weeks, and change one-third to one-half of the water each time. >>>More
