Question

41) Из двух деревень расстояние между которыми составляет 3 км 600 м одновременно отправились в путь двое велосипедистов. Если скорость одного из велосипедистов 140 м/мин, а скорость другого 100 м/мин, то сколько метров пути проехал каждый велосипедист ?

Answer 1

3 км 600 м=3600 м

140+100=240 м/мин -совместная скорость обоих велосипедистов

3600/240=15 мин - время затраченное обеими велосипедистами до встречи

140*15=2100м -путь который  проехал первый велосипедист

100*15=1500м -путь который  проехал второй велосипедист

Ответ:2100м -путь который  проехал первый велосипедист

1500м -путь который  проехал второй велосипедист

Answer 2

Problem Analysis

We are given that two cyclists simultaneously set off from two villages, and the distance between the villages is 3 km 600 m. The speed of one cyclist is 140 m/min, and the speed of the other cyclist is 100 m/min. We need to find out how many meters each cyclist traveled.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's assume that cyclist A is traveling at a speed of 140 m/min and cyclist B is traveling at a speed of 100 m/min.

Let's calculate the distance traveled by cyclist A and cyclist B.

Calculation

The distance between the two villages is 3 km 600 m, which is equal to 3,600 m.

Let's calculate the time taken by both cyclists to cover this distance.

The time taken by cyclist A can be calculated as:

Time taken by cyclist A = Distance / Speed of cyclist A

Substituting the values, we get:

Time taken by cyclist A = 3,600 m / 140 m/min

Calculating this, we find:

Time taken by cyclist A = 25.71 min

Similarly, the time taken by cyclist B can be calculated as:

Time taken by cyclist B = Distance / Speed of cyclist B

Substituting the values, we get:

Time taken by cyclist B = 3,600 m / 100 m/min

Calculating this, we find:

Time taken by cyclist B = 36 min

Now, let's calculate the distance traveled by each cyclist.

The distance traveled by cyclist A can be calculated as:

Distance traveled by cyclist A = Speed of cyclist A × Time taken by cyclist A

Substituting the values, we get:

Distance traveled by cyclist A = 140 m/min × 25.71 min

Calculating this, we find:

Distance traveled by cyclist A = 3,599.4 m

The distance traveled by cyclist B can be calculated as:

Distance traveled by cyclist B = Speed of cyclist B × Time taken by cyclist B

Substituting the values, we get:

Distance traveled by cyclist B = 100 m/min × 36 min

Calculating this, we find:

Distance traveled by cyclist B = 3,600 m

Answer

Therefore, the distance traveled by each cyclist is as follows: - Cyclist A traveled 3,599.4 meters. - Cyclist B traveled 3,600 meters.
