Question

Из двух посёлков выехали одновременно навстречу друг другу 2 всадника.1 ехал со скоростью 200 м.мин,а второй проежал в минуту на 20 м меньше.всадники встретились через 50 минут. какое расстояние между посёлками?

Answer 1

1)200-20=180

2)180+200=380

3)380*50=19000

Answer 2

200 - 20 = 180 (м/мин.) - скорость второго всадника.

(180 + 200) * 50 = 19000 (м) - расстояние между посёлками.

19000 м. = 19 км.

Ответ : 19 км расстояние между посёлками. 

Answer 3

Problem Analysis

We have two riders who start simultaneously from two 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 = 10,000 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 = 9,000 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 = 10,000 + 9,000

Simplifying the equation:

d = 19,000 meters

Answer

The distance between the two villages is 19,000 meters.
