Question

ПОМОГИТЕЕЕ ПЖ ПОЖАЛУЙСТА Из двух сёл, расстояние между которыми 30 км, навстречу друг другу одновременно вышли два пешехода и встретились через 3 ч. Скорость первого пешехода — 5 км/ч. Найди скорость второго пешехода.

Answer 1

Ответ:

5 км/ч скорость второго пешехода.

Пошаговое объяснение:

5*3=15 (км) прошел первый пешеход.

30-15=15 (км) прошел второй пешеход.

15/3=5 (км/ч) скорость второго пешехода.

Answer 2

Problem Analysis

We have two pedestrians who start walking towards each other from two different villages. The distance between the villages is 30 km. They meet each other after 3 hours. The speed of the first pedestrian is given as 5 km/h. We need to find the speed of the second pedestrian.

Solution

Let's assume the speed of the second pedestrian is x km/h.

The total distance covered by the first pedestrian in 3 hours is 5 km/h * 3 h = 15 km.

Since the total distance between the two villages is 30 km, the second pedestrian must have covered the remaining distance of 30 km - 15 km = 15 km in 3 hours.

Therefore, the speed of the second pedestrian is 15 km / 3 h = 5 km/h.

So, the speed of the second pedestrian is also 5 km/h.

Answer

The speed of the second pedestrian is 5 km/h.
