Question

Из двух сёл, расстояние между которыми 45 км, навстречу друг другу одновременно вышли два пешехода и встретились через 5 ч. Скорость первого пешехода — 3 км/ч. Найди скорость второго пешехода.

Answer 1

Ответ:

6 км/ч

Пошаговое объяснение:

1)5*3=15 км - прошел 1 пешеход

2)45-15+30 км - прошел 2 пешеход

3)30/5=6 км/ч - скорость 2 пешехода

Вроде так.

Answer 2

Problem Analysis

We are given that two pedestrians start walking towards each other from two villages that are 45 km apart. They meet after 5 hours. The speed of the first pedestrian is 3 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.

Since the two pedestrians are walking towards each other, their combined speed is the sum of their individual speeds. Therefore, the combined speed of the two pedestrians is 3 + x km/h.

We know that the distance between the two villages is 45
