Question

Из двух поселков расстояние между которыми равно 3 км Одновременно навстречу друг другу вышли два пешехода один из них двигался со скоростью 5 километров час а второй 4 километров час Какое расстояние будет между пешеходными через 2 часа после начала движения

Answer 1

1.5+4=9км/ч скорость сближения
2.9*2=18км-они пройдут через 2 часа
3.18-3=15км такое расстояние будет между ними

Answer 2

Должны встретиться. 5х2=10 км а 4х2=8 км. А это гораздо больше чем расстояние между поселками

Answer 3

I will answer in detail. From two villages, the distance between which is 3 km, two pedestrians simultaneously walked towards each other. One of them moved at a speed of 5 kilometers per hour and the other at 4 kilometers per hour. What will be the distance between the pedestrians after 2 hours from the start of the movement?

To solve this problem, we need to find the relative speed and the distance covered by the pedestrians in 2 hours. The relative speed is the sum of the speeds of the pedestrians moving in opposite directions. The distance covered is the product of the relative speed and the time. The distance between the pedestrians is the difference between the initial distance and the distance covered.

The relative speed is 5 + 4 = 9 km/h. The distance covered is 9 * 2 = 18 km. The distance between the pedestrians is 3 - 18 = -15 km. This means that the pedestrians have crossed each other and moved 15 km away from their initial positions. Therefore, the answer is -15 km.
