Question

2 пешехода вышли одновременно из 2 деревень навстречу друг другу.Один шёл со скоростью 5 км в час, другой 4 км в час.встретились они через 3 часа.Каково расстояние между деревнями?

Answer 1

Общая скорость 5+4=9(км/час)
За 3 часа они пройдут
9*3=27(км)
Расстояние 27км.

Answer 2

5х9=15км  прошел один пешеход за 3 часа

4х3=12км прошел второй пешеход за 3 чача
15+12=27 км
Ответ расстояние между деревнями 27 км

Answer 3

Problem Analysis

We have two pedestrians walking towards each other from two different villages. One pedestrian is walking at a speed of 5 km/h, while the other is walking at a speed of 4 km/h. They meet each other after 3 hours. We need to find the distance between the villages.

Solution

To find the distance between the villages, we can use the formula: Distance = Speed * Time.

Let's calculate the distances covered by each pedestrian:

- The first pedestrian walks at a speed of 5 km/h for 3 hours, so the distance covered by the first pedestrian is 5 km/h * 3 hours = 15 km. - The second pedestrian walks at a speed of 4 km/h for 3 hours, so the distance covered by the second pedestrian is 4 km/h * 3 hours = 12 km.

Since they meet each other, the sum of the distances covered by both pedestrians should be equal to the total distance between the villages. Therefore, the distance between the villages is 15 km + 12 km = 27 km.

Answer

The distance between the villages is 27 km.
