Question

Расстояние между селами 25 километров скорость одного пешехода 5 километров в час через 2 часа после начала движения расстояние между пешеходными стало равно 3 километров Определите скорость другого пешехода

Answer 1

1) 5*2=10 км (спустя 10 км расстояние между пешеходами сократилось до 3 км)
2) 25-(10+3) =12 км- прошёл 2 пешеход
3) 12:2=6 км/ч - скорость 2 пешехода

Answer 2

Problem Analysis

We are given the following information: - The distance between two villages is 25 kilometers. - The speed of one pedestrian is 5 kilometers per hour. - After 2 hours of walking, the distance between the pedestrians becomes 3 kilometers.

We need to determine the speed of the other pedestrian.

Solution

Let's assume the speed of the other pedestrian is x kilometers per hour.

After 2 hours of walking, the first pedestrian has covered a distance of 5 kilometers per hour * 2 hours = 10 kilometers.

The remaining distance between the pedestrians is 25 kilometers - 10 kilometers = 15 kilometers.

Since the remaining distance is 15 kilometers and the time taken is 2 hours, we can calculate the speed of the other pedestrian using the formula:

Speed = Distance / Time

x = 15 kilometers / 2 hours = 7.5 kilometers per hour

Therefore, the speed of the other pedestrian is 7.5 kilometers per hour.

Answer

The speed of the other pedestrian is 7.5 kilometers per hour.
