Question

из одного посёлка вышли в одно и то же время в противоположных направлениях два пешехода. скорость одного 5 км.час, а скорость другого 6 км.час. Через сколько часов расстояние между ними будет равно 30 км.

Answer 1

Скорость удаления пешеходов 5+6=11 км/ч
расстояние между пешеходами 30 км будет через 30/11 часов или
примерно 2 часа 44 минуты

Answer 2

Problem Analysis

Two pedestrians start walking in opposite directions from the same village at the same time. One pedestrian walks at a speed of 5 km/h, while the other walks at a speed of 6 km/h. We need to determine how many hours it will take for the distance between them to be 30 km.

Solution

To solve this problem, we can use the formula: distance = speed × time. Let's assume that it takes t hours for the distance between the pedestrians to be 30 km.

The distance covered by the first pedestrian in t hours is given by: 5t km.

The distance covered by the second pedestrian in t hours is given by: 6t km.

According to the problem, the sum of these distances should be equal to 30 km:

5t + 6t = 30

Simplifying the equation:

11t = 30

Solving for t:

t = 30 / 11

Therefore, it will take approximately 2.73 hours for the distance between the pedestrians to be 30 km.

Answer

It will take approximately 2.73 hours for the distance between the two pedestrians to be 30 km.
