Question

Из одного пункта одновременно в противоположном направлении отправился велосипедист и пешеход пешеход двигался со скоростью 3 километров час велосипедист со скоростью 4 раза больше Какое расстояние будет между ними через 2 часа после начала движения

Answer 1

3 км/ч * 2 ч + 3 км/ч * 4 * 2 ч = 30 км 

Answer 2

Problem Analysis

We are given the following information: - A pedestrian is moving at a speed of 3 kilometers per hour. - A cyclist is moving at a speed that is 4 times greater than the pedestrian's speed.

We need to find the distance between them after 2 hours.

Solution

To find the distance between the pedestrian and the cyclist after 2 hours, we need to calculate the distance each of them has traveled.

The distance traveled by the pedestrian can be calculated using the formula: Distance = Speed × Time

Substituting the given values: Distance (pedestrian) = 3 km/h × 2 h = 6 km

The distance traveled by the cyclist can be calculated using the same formula: Distance (cyclist) = Speed × Time

Substituting the given values: Distance (cyclist) = (4 × 3) km/h × 2 h = 24 km

Therefore, the distance between the pedestrian and the cyclist after 2 hours will be the difference between their distances traveled: Distance (between them) = Distance (cyclist) - Distance (pedestrian)

Substituting the calculated values: Distance (between them) = 24 km - 6 km = 18 km

So, the distance between the pedestrian and the cyclist after 2 hours will be 18 kilometers.

Answer

The distance between the pedestrian and the cyclist after 2 hours will be 18 kilometers.
