Question

Из пункта A вышел пешеход со скоростью 5 км/ч. Через 3 ч. за ним выехал велосипедист со скоростью 15 км/ч. На каком расстоянии от А велосипедист догонит пешехода

Answer 1

....?.....!...........

Answer 2

1 действия 15 плюс 5 равно 20 км в час общая скорость 2 действия 20 умножить на 3 равно 60 км расстояние ответ: на 60 километров расстояние от а велосипедист догонит пешехода

Answer 3

Problem Analysis

We are given that a pedestrian walks at a speed of 5 km/h and a cyclist rides at a speed of 15 km/h. We need to determine the distance at which the cyclist overtakes the pedestrian after 3 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by the pedestrian and the cyclist after 3 hours.

The pedestrian's distance = 5 km/h × 3 h = 15 km.

The cyclist's distance = 15 km/h × 3 h = 45 km.

Since the cyclist is traveling faster than the pedestrian, the cyclist will eventually catch up to the pedestrian.

To find the distance at which the cyclist overtakes the pedestrian, we need to find the difference in their distances.

The difference in distance = cyclist's distance - pedestrian's distance = 45 km - 15 km = 30 km.

Therefore, the cyclist will overtake the pedestrian at a distance of 30 km from point A.

Answer

The cyclist will overtake the pedestrian at a distance of 30 km from point A.
