Question

От станции в направление поселка расстояние до которого 22 км вышел пешеход со скоростью 4 км в час. Через 2 часа на встречу ему с поселка вышел велосипедист со скоростью 10 км в час. Через сколько часов после своего выхода пешеход встретит велосипедиста.

Answer 2

За 2ч пешеход пройдет
2*4=8 км
оставшееся расстояние
22-8=14 км
скорость сближения
10+4=14 км/ч
14/14=1 час пройдет до встречи с момента старта велосипеда
2+1=3 часа после своего выхода пешеход встретит велосипед

Answer 3

Problem Analysis

We are given that a pedestrian walks at a speed of 4 km/h and starts walking from a station towards a village that is 22 km away. After 2 hours, a cyclist starts from the village and rides towards the pedestrian at a speed of 10 km/h. We need to determine how many hours after the pedestrian starts walking they will meet the cyclist.

Solution

To solve this problem, we can use the formula: time = distance / speed. We will calculate the time it takes for both the pedestrian and the cyclist to cover the distance between them and find the time at which they meet.

Let's calculate the time it takes for the pedestrian to cover the distance of 22 km: - Distance: 22 km - Speed: 4 km/h - Time = Distance / Speed = 22 km / 4 km/h = 5.5 hours

Now, let's calculate the time it takes for the cyclist to cover the distance from the village to the pedestrian: - Distance: 22 km - Speed: 10 km/h - Time = Distance / Speed = 22 km / 10 km/h = 2.2 hours

Since the cyclist starts 2 hours after the pedestrian, we need to add this time to the time it takes for the cyclist to cover the distance: - Total time = 2.2 hours + 2 hours = 4.2 hours

Therefore, the pedestrian will meet the cyclist 4.2 hours after they start walking.

Answer

The pedestrian will meet the cyclist 4.2 hours after they start walking.
