В 6 ч утра трактор выехал из одного села в другое и ехал со скоростью 9 км в час. В 8 ч утра из этого же села выехал вслед за ним велосипедист, который догнал трактор в 11 ч утра. С какой скоростью ехал велосипедист?

Answer 1

Ответ: 15 км/ч

5часов(время трактора)*9км/ч=45(км)

45/3=15км/ч

Answer 2

Problem Analysis

We are given the following information: - A tractor left one village and traveled at a speed of 9 km/h from 6 am. - At 8 am, a cyclist left the same village and caught up with the tractor at 11 am.

We need to find the speed at which the cyclist was traveling.

Solution

To find the speed of the cyclist, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled by the tractor from 6 am to 11 am.

The tractor traveled for 5 hours at a speed of 9 km/h, so the distance traveled by the tractor is:

Distance = Speed * Time = 9 km/h * 5 hours = 45 km

Since the cyclist caught up with the tractor at 11 am, the cyclist also traveled the same distance of 45 km.

Now, let's calculate the time taken by the cyclist to cover this distance.

The cyclist started at 8 am and caught up with the tractor at 11 am, so the time taken by the cyclist is:

Time = 11 am - 8 am = 3 hours

Finally, we can calculate the speed of the cyclist using the formula:

Speed = Distance / Time = 45 km / 3 hours = 15 km/h

Therefore, the cyclist was traveling at a speed of 15 km/h.

Answer

The cyclist was traveling at a speed of 15 km/h.
