Anonymous users2024-02-07Solution: Let the full distance = x
Distance traveled = 20% x 3 2 x 40
The distance already traveled is 1 4 of the total distance
So (solution: x=1200.)
A: The two ports are 1,200 meters apart.

Anonymous users2024-02-05After another 1 hour, the ratio of the untraveled distance to the traveled distance is 3:1 traveled: the whole journey = 1:4
40/(1/4-20%)=800km
The steamer sailed from port A to port B at a speed of 40 meters per hour, and after traveling 20% of the whole journey, it took another 3 or 2 hours, at which point the ratio of the untraveled distance to the traveled distance was 3:1. How many kilometers are the two ports apart?
40*3/2)/(1/4-1/5)=1200km

Anonymous users2024-02-04Current ship technology:
The speed of an ordinary general cargo ship is 12 15 knots, that is, 22 27 kilometers per hour, and the speed of a large container ship is 20 28 knots, that is, 36 52 kilometers per hour, and the maximum speed of a large nuclear-powered aircraft carrier can reach 32 35 knots, or 60 65 kilometers per hour.
The speed of the ordinary ** is between 20 and 30 knots, which is 36 55 kilometers per hour, and the speed of a large cruise ship is about the same as that of a large container.
1 knot is 1 nautical mile per hour, 1 nautical mile kilometer.

Anonymous users2024-02-02Summary. A ship travels 28 kilometers in one hour and about 336 kilometers in 12 hours.
A ship can travel 28 kilometers in 1 hour and about 300 kilometers in 12 hours.
A ship travels 28 kilometers in one hour and about 336 kilometers in 12 hours.
Kiss, the analysis is as follows: 28x12=336km
I want to ask if it's right or wrong.
is wrong. A ship travels 28 kilometers in one hour and about 336 kilometers in 12 hours.
Not 300 ha.
Calculation method: 28 kilometers in one hour, 28 12 = 336 kilometers in 12 hours. So it's wrong.
There is an approximate approximation, and the estimate of 336 is an accurate number, not an approximation.
If a ship travels 28 kilometers in 1 hour, it can travel about 300 kilometers in 12 hours.
There is no problem with this estimate.
is the right <>
Is it right to add what is going on?
No need to add ifs.
It's a bit of a mess, right or wrong now.
A ship can travel 28 kilometers in 1 hour and about 300 kilometers in 12 hours.
It can be processed correctly.

Anonymous users2024-02-01Summary. Hello, the answer is as follows: x 5 = 5x (km) Answer: A ship sails x km per hour, then sails (5x) km for 5 hours.
If a ship travels x kilometers per hour, how many kilometers does it travel in 5 hours.
Hello, the answer is as follows: x 5 = 5x (km) Answer: A ship sails x km per hour, then sails (5x) km for 5 hours.
Dear, practice analysis shouting resistance: Hello, this question belongs to the speed band is given x kilometers per hour and the time is 5 hours, find the distance. It is calculated by using the old stroke formula: distance = speed time.

The two ports of A and B are located x kilometers apart.

5% x = 40
x= 20 x 40 = 800 km

It depends on your criteria. Just like configuring a computer, the good ones are a little more expensive, and the ordinary ones are cheaper. The same goes for an aircraft carrier, in fact, its shell is not expensive, but it is the various electronic systems, sensors, etc. on its ship. >>>More
Not a copycat. To briefly reside, the Varyag is the second of the Kuznetsov class of aircraft carriers built during the Soviet era (the first is the "Kuznetsov", which is now in service with the Russian Navy), but it was not completed, and it was 68% built by the time of the collapse of the Soviet Union. Later, Russia ran out of money, didn't want it, and Ukraine's own naval strategy didn't need such a big ship, so it was sold to China, but the power system, the ** system, and the electronic system were dismantled, and it was basically sold to China as an empty shell. >>>More
