Question

Из деревни вышел пешеход,а через 2 часа выехал велосипедист.Скорость велосипедиста 10 км/ч,а скорость пешехода 5 км/ч.Через сколько часов после выезда велосипедист догонит пешехода.

Answer 1

5х2=10 км-расстояние между пешеходом и велосипедистом
10-5=5 км ч -скорость сближения
10/5=2
Ответ:Через 2 часа
Пожалуйста,поблагодари и поставь как лучший

Answer 2

Велосипедист догонит его через час он его догонит

Answer 3

Problem Analysis

The problem involves a pedestrian and a cyclist. The pedestrian starts walking from a village, and after 2 hours, the cyclist starts riding at a speed of 10 km/h. The pedestrian's speed is 5 km/h. We need to determine how many hours after the cyclist starts riding will they catch up to the pedestrian.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed of the cyclist with respect to the pedestrian is the difference between their speeds.

The formula to calculate the time taken for the cyclist to catch up to the pedestrian is: Time = Distance / Relative Speed

Calculation

The distance covered by the pedestrian in 2 hours = 5 km/h * 2 h = 10 km

Now, the relative speed of the cyclist with respect to the pedestrian = 10 km/h - 5 km/h = 5 km/h

Using the formula, we can calculate the time taken for the cyclist to catch up to the pedestrian: Time = 10 km / 5 km/h = 2 hours

Answer

The cyclist will catch up to the pedestrian 2 hours after starting to ride.
