Primary 5 Year Contest Questions Tortoise and Hare Race

The rabbit only ran 10000-100 = 9900 meters in total, and the turtle could only run 9900 5 = 1980 meters during this time, so the rest of the distance was run while the rabbit was sleeping, a total of 10000-1980 = 8020 meters.

755 m Rabbits sleep at 3775 m place.

Suppose the turtle velocity is V, then the rabbit is 5V

5000+vt=5vt+100

Calculate vt=1225

That is, the turtle walked another 1225 meters.

Plus 5000 meters ahead, that is, 6225 meters, so the rabbit starts sleeping at 3775 meters, then the tortoise speed is 1 5 rabbits, so the tortoise walks 755 meters.

If you ask how much the tortoise walked while the rabbit was sleeping, it would be 5000 + 3775-755 = 8020 meters.

10000-[(10000-100) 5] = 8020 meters.

5000 meters is a useless condition, but if the rabbit is required to sleep somewhere from the starting point, then 5000 meters is useful.

When the rabbit wakes up, the distance from the tortoise to the end point is (5000-100) (5-1) = 1225 meters, and the distance from the starting point when the rabbit sleeps is 10000-5000-1225=3775 meters, and the distance between the turtle and the starting point is 3775 5*4=3020 meters.

During the time when the rabbit slept, the tortoise ran 3020 + 5000 = 8020 meters.

Answer: Suppose that when the rabbit wakes up and starts running, the distance between the tortoise and the end point is ss-100 = (s+5000) 5s = 1125 meters, so the distance between the rabbit sleeping place and the starting point is: 10000-5000-1125 = 3875 meters, so the tortoise runs 3875 5 4 + 5000 = 8100 meters while the rabbit sleeps.

Solution: 5000-100=4500 (m).

4500 4 = 1125 (m).

10000-1125-5000 = 3875 (m) 3875 5 = 775 (m).

Answer: While the rabbit was sleeping, the turtle ran 775 meters.

1 400/2-350/100 =

2 (x + 4 starts) squared - x = 40x = 349 area.

8020 is simple, let the speed of the turtle be V, then the rabbit's is 5V; Let the rabbit start sleeping after running T1 time, sleep T2 time, and finally chase T3 time 100 meters behind the turtle; By the relation there is for rabbits: 5v * t1 + 5v * t3 = 10000 - 100 ·· 1) For tortoise: v(t1 + t2 + t3) = 10000 ·· 2) The distance that the tortoise runs while the rabbit is sleeping is:

v * t2 from (1) (2) gives v * t2 = 8020 (m).

The allusion to the tortoise and rabbit race can have many questions that can be asked, such as why did the tortoise win and why did the hare lose?

What are the reasons for the failure?

Is it this type? If yes:

20 75) (320-20) = 5 minutes.

The rabbit can catch up with the tortoise five minutes after departure.

The tortoise and rabbit race, the whole kilometer, the rabbit runs 20 kilometers per hour, the turtle Weixun runs 3 kilometers per hour, and the turtle keeps running; The rabbit runs and plays, it runs for 1 minute and then plays for 15 minutes, then runs for 2 minutes and then plays for 15 minutes, then runs for another 3 minutes and then plays for 15 minutes,..So how many minutes is it faster to arrive first and not reach the finish line than to reach the finish line later?

Answer & Analysis:

Turtle time: minutes); Rabbit Kiriyama Na ran a total of : minutes).

And we have: according to the question conditions, from the above equation we can know that the rabbit rested a total of 5 times, a total of 15 5 = 75 (minutes).So when rabbits share:

minutes).The rabbit reaches the end point first, faster than the tortoise that reaches the end point later: minutes).

On the weekend, my mother, me, Jiahui, and Jiaqi had just finished eating, and they all sat down and talked together. Perhaps this atmosphere infected Mu Xiaoxiao and Jiaqi, who stood on the sofa and began to "go crazy". She said out loud with a mischievous face

You're done, it's time for me to talk. Let me tell you the story of the tortoise and hare race.

Jiaqi is not a big person, and it is still okay to tell stories, so we all sat down seriously and said: Okay, okay.

So, Jiaqi, the "king of stories", began to tell us stories and raise the cover. "In a wood, the animals are having a sports day, and the rabbits and tortoises are racing," she says. ”

Hearing this, I asked a question, I said Jiaqi, since it is a sports meeting, why are there only two rabbits and turtles running, shouldn't everyone run together? If you look at the school sports day, it's usually a lot of people running together.

Jiaqi was stunned, thought about it, and said with a smile: I don't know, ask my sister.

asked my sister, and my sister was also stunned. I said let's look it up. Sister Jiahui hurried up, only to realize that it was the arrogant rabbit who provoked the turtle and said: I run fast, you will never be able to outrun me. The turtle said, "Sooner or later, I will surpass you."

Thus was born this famous tortoise and hare race.

Thanks to them, I can revisit these stories, and I can probably learn from them and always have some inspiration. Just like this story of the tortoise and rabbit race, when I was a child, I thought that it was the hard-working tortoise that outran the arrogant rabbit.

Now I feel that if a person has talent in some aspect, he must not be arrogant and no one is in sight, and arrogant people are always defeated by their own arrogance; If a person is not talented in a certain aspect, do not feel inferior to it, because as long as you don't give up your efforts, you have a chance to succeed.

Zeng Guofan said in the Six Precepts: All talented people in the world are defeated by arrogant words, and mediocre people in the world are defeated by lazy words. Therefore, we should take it as a warning, and abstain from arrogance and laziness.

Summary. There are four different outcomes of the tortoise and hare race: 1. The tortoise wins The tortoise has a rocket propulsion device installed on its body 2. The tortoise wins The rabbit's friend intends to try to thwart the tortoise, and the tortoise knows about this, so the tortoise disguises himself as a rabbit.

The hare thinks that the tortoise's companion will do the same, so he disguises himself as a tortoise 3, the tortoise wins is a genetically mutated tortoise 4, the tortoise wins the <> in the water race

Four different results of the tortoise and hare second race.

The rabbit thinks that the turtle's companion of the Envy Hu faction will do the same, so he disguises himself as a turtle 3, the turtle wins is a genetically mutated turtle 4, the turtle wins the <> in the water race

The Tortoise and Hare Race is an intriguing fable about a proud rabbit and a persevering baby tortoise. <>

Zanxun erects Lu Tong].

The turtle climbed 96 8 = 12 minutes.

The rabbit walked 96 meters and should have used 96 35=

Since I slept for another 10 minutes, it took more than 12 minutes.

Here's the secret: the tortoise eventually catches up with the rabbit.

Separate calculations will do. The rabbit ran for 10 minutes and stopped to sleep for 200 minutes, during which the rabbit ran a total of (330*10=) 3300 meters, and the turtle climbed (30*210=) 6300 meters.

Let the place of catching up be x meters away from the starting point, and the column equation: (x-3300) 330=(x-6300) 30, and solve: x=6600, then there is still 7000-6600=400 meters from the end point.

It is one of the basic ideas of mathematics to use the idea of equations.
