Question

Два пешехода вышли одновременно из одного места в противоположных направлениях через 0,8 часов расстояние между ними стало равным 6,8 километров Скорость одного пешехода была в одну целую пять десятых раза больше скорости другого Найдите скорость каждого пешехода

Answer 2

Суммарная скорость пешеходов: 6,8 / 0,8 = 8,5 км/ч
Пусть скорость более медленного пешехода будет х, тогда более быстрого - 1,5х.
Составим небольшое уравнение
х + 1,5х = 8,5
2,5х = 8,5
х = 3,4 км/ч
Скорость второго пешехода 8,5 - 3,4 = 5,1 км/ч

Answer 3

Problem Analysis

We have two pedestrians who start walking simultaneously from the same point in opposite directions. After 0.8 hours, the distance between them is 6.8 kilometers. The speed of one pedestrian is 1.5 times greater than the speed of the other pedestrian. We need to find the speed of each pedestrian.

Solution

Let's assume the speed of the slower pedestrian is x km/h. Therefore, the speed of the faster pedestrian would be 1.5x km/h.

We can use the formula distance = speed × time to calculate the distance traveled by each pedestrian.

For the slower pedestrian: - Distance = x km/h × 0.8 h = 0.8x km

For the faster pedestrian: - Distance = 1.5x km/h × 0.8 h = 1.2x km

According to the problem, the total distance between the two pedestrians after 0.8 hours is 6.8 kilometers. Therefore, we can set up the equation:

0.8x + 1.2x = 6.8

Simplifying the equation: 2x = 6.8 x = 6.8 / 2 x = 3.4

So, the speed of the slower pedestrian is 3.4 km/h and the speed of the faster pedestrian is 1.5 × 3.4 = 5.1 km/h.

Therefore, the speed of each pedestrian is: - Slower pedestrian: 3.4 km/h - Faster pedestrian: 5.1 km/h

Answer

The speed of the slower pedestrian is 3.4 km/h and the speed of the faster pedestrian is 5.1 km/h.
