Question

Два пешехода вышли одновременно из одного пункта в противоположное направление первый шел со скоростью 5 километров час а второй 4 км расстояние между ними будет через час: через 2 часа через 3 часа

Answer 1

Отметь как лучший ответ
1.Разность U=5-4=1 км/ч
2.1*1=1км
3.1*2=2
3.1*5=5
Ответ:1,2,5

Answer 2

Так как они идут в противоположные стороны, то отдаляются с суммарной скоростью - 4+5=9, а значит за час это будет 9 км, за 2 часа - 9*2=18 и за 3 часа - 27 км

Answer 3

Calculation of the Distance between Two Pedestrians

To calculate the distance between two pedestrians who start walking simultaneously in opposite directions, we can use the formula:

Distance = Speed x Time

Let's calculate the distance between the two pedestrians at different time intervals:

1. After 1 hour: - The first pedestrian walks at a speed of 5 kilometers per hour. - The second pedestrian walks at a speed of 4 kilometers per hour. - Therefore, the distance between them after 1 hour is (5 km/h + 4 km/h) x 1 hour = 9 kilometers.

2. After 2 hours: - The first pedestrian walks at a speed of 5 kilometers per hour. - The second pedestrian walks at a speed of 4 kilometers per hour. - Therefore, the distance between them after 2 hours is (5 km/h + 4 km/h) x 2 hours = 18 kilometers.

3. After 3 hours: - The first pedestrian walks at a speed of 5 kilometers per hour. - The second pedestrian walks at a speed of 4 kilometers per hour. - Therefore, the distance between them after 3 hours is (5 km/h + 4 km/h) x 3 hours = 27 kilometers.

So, the distance between the two pedestrians will be 9 kilometers after 1 hour, 18 kilometers after 2 hours, and 27 kilometers after 3 hours.
