Question

Из поселка в противоположных направлениях вышел пешеход и выехал велосипедист через 4 часа расстаяние между ними составляло 56 км с какой скоростью шёл пешеход если велосипедист ехал со скоростью 10 км/ч

Answer 1

Я думаю
56÷4=14
14-10=4 кл/
Ответ: со скоростью 4 кл/ч шёл пешеход

Answer 2

1)10*4=40км
-столько проехал велосипедист 
2)56-40=16км
-столько прошел пешеход 
3)16:4=4км/ч
Ответ: 4км/ч

Answer 3

Problem Analysis

We are given the following information: - A pedestrian and a cyclist start from opposite directions. - After 4 hours, the distance between them is 56 km. - The cyclist is traveling at a speed of 10 km/h.

We need to find the speed at which the pedestrian is walking.

Solution

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

In 4 hours, the cyclist would have traveled a distance of 10 km/h * 4 hours = 40 km.

The total distance between the pedestrian and the cyclist after 4 hours is 56 km.

Therefore, the distance traveled by the pedestrian in 4 hours is 56 km - 40 km = 16 km.

Using the formula distance = speed * time, we can write the equation:

16 km = x km/h * 4 hours

To find the speed of the pedestrian, we can rearrange the equation:

x km/h = 16 km / 4 hours

Simplifying the equation, we get:

x km/h = 4 km/h

Therefore, the pedestrian is walking at a speed of 4 km/h.

Answer

The pedestrian is walking at a speed of 4 km/h.

Explanation

After 4 hours, the cyclist has traveled a distance of 40 km at a speed of 10 km/h The total distance between the pedestrian and the cyclist after 4 hours is 56 km. Therefore, the distance traveled by the pedestrian in 4 hours is 56 km - 40 km = 16 km. Using the formula distance = speed * time, we can calculate the speed of the pedestrian as 16 km / 4 hours = 4 km/h.
