Question

Как решать задачу такую:2 велосипедиста выехали одновременно навстречу друг другу из поселков,расстояние между которыми 7км,и встретились через 20мин.Один велосипедист ехал со скоростью 200м/мин.Определи скорость 2 велосипедиста.

Answer 1

7 км= 7000 метров
200*20=4000(м) проехал один велосипедист
7000-4000= 3000(м) проехал второй
3000/20=150(м/мин) скорость второго

Answer 2

Solving the Problem of Two Cyclists Meeting

To solve this problem, we can use the formula:

Distance = Speed × Time

We know that the total distance between the two cyclists is 7 km and they meet after 20 minutes. We also know the speed of one of the cyclists, which is 200 m/min. Using this information, we can calculate the speed of the second cyclist.

Calculating the Speed of the Second Cyclist

Let's denote the speed of the second cyclist as x m/min.

The first cyclist covers a distance of 200 m/min × 20 min = 4000 m = 4 km.

So, the remaining distance for the second cyclist to cover is 7 km - 4 km = 3 km.

Using the formula Distance = Speed × Time, we can calculate the speed of the second cyclist:

3 km = x m/min × 20 min

Solving for x:

x = 3 km / 20 min = 3000 m / 20 min = 150 m/min

Therefore, the speed of the second cyclist is 150 m/min.

So, the speed of the second cyclist is 150 m/min.
