Question

Фото вышли Одновременно навстречу друг другу и встретились Через 2,5 часов скорость первого пешехода равна 4,2 километров час а скорость второго 5,2 километров час Какое расстояние было между пешеходами в начале движения

Answer 1

1) 4,2 • 2,5= 10,5 (км)- прошёл первый пешеход за 2,5 часа
2) 5,2 • 2,5= 13 (км)- прошёл второй пешеход за 2,5 часа
3) 10,5 + 13 = 23,5 (км)- расстояние между ними
Ответ: 23, 5 км

Answer 2

1) 2,5×4,2=10,5(км)-прошел первый пешеход.
2) 2,5×5,2=13(км)-прошел второй пешеход.
3)10,5+13=23,5(км)-расстояние между пешеходами в начале.
Ответ:23,5 км.

Answer 3

Problem Analysis

We are given the following information: - Two pedestrians start walking towards each other. - After 2.5 hours, the first pedestrian has covered a distance of 4.2 kilometers at a speed of 4.2 kilometers per hour. - The second pedestrian has covered a distance of 5.2 kilometers at a speed of 5.2 kilometers per hour.

We need to find the initial distance between the pedestrians when they started walking.

Solution

To find the initial distance between the pedestrians, we can use the formula:

Distance = Speed × Time

Let's calculate the distances covered by each pedestrian:

- Distance covered by the first pedestrian = Speed of the first pedestrian × Time = 4.2 km/h × 2.5 h = 10.5 km - Distance covered by the second pedestrian = Speed of the second pedestrian × Time = 5.2 km/h × 2.5 h = 13 km

The initial distance between the pedestrians can be calculated by adding the distances covered by each pedestrian:

Initial distance = Distance covered by the first pedestrian + Distance covered by the second pedestrian

Initial distance = 10.5 km + 13 km = 23.5 km

Therefore, the initial distance between the pedestrians when they started walking was 23.5 kilometers.

Answer

The initial distance between the pedestrians when they started walking was 23.5 kilometers.
