Question

Из двух поселков выехали одновременно навстречу друг друга два всадника.первы ехал со скоростью 200 м/мин,а второй проезжал в минуту на 20 м меньше.всадники встретились через 50 минут.найди расстояние между поселками.

Answer 1

1) 200*50 = 10 000 (м) - проехал первый всадник
2) 200- 20 =180 (м/мин) - скорость второго всадника
3) 180*50 = 9 000 (м)  -проехал второй всадник
4) 10 000 + 9 000 = 19 000 (м) -расстояние между двумя поселками
Ответ: расстояние между поселками 19 000м, т.е. 19 км.

Answer 2

Problem Analysis

We have two riders who start simultaneously from two different villages and ride towards each other. The first rider travels at a speed of 200 m/min, while the second rider travels 20 m/min slower than the first rider. They meet after 50 minutes. We need to find the distance between the two villages.

Solution

Let's assume the distance between the two villages is d meters.

The first rider travels at a speed of 200 m/min, so in 50 minutes, the first rider covers a distance of 200 * 50 = 10000 meters.

The second rider travels at a speed 20 m/min slower than the first rider, so the second rider's speed is 200 - 20 = 180 m/min. In 50 minutes, the second rider covers a distance of 180 * 50 = 9000 meters.

Since they meet after 50 minutes, the total distance covered by both riders is equal to the distance between the two villages. Therefore, we can write the equation:

d = 10000 + 9000

Simplifying the equation:

d = 19000 meters

Answer

The distance between the two villages is 19000 meters.
