Question

из двух сел одновременно вышли навстречу друг к другу вышли 2 пешехода и встретились через 3 часа. Расстояние между ними 27 км. найдите найдите скорость пешеходов если скорость одного пешехода на 1 км/ч больше чем у второго

Answer 1

Ответ:

Пошаговое объяснение:

Х+х+1=27÷3

2х=9-1=8

Х=8÷2=4 км/час скорость 2 пешехода

4+1=5км/час скорость 1 пешехода

2 способ

27÷3=9 км/час скорость сближения

(9-1)÷2=4км/час скорость 2 пешехода

4+1=5км/час скорость 1 пешехода

Answer 2

Problem Analysis

We have two pedestrians who start walking towards each other simultaneously. They meet after 3 hours, and the distance between them is 27 km. We need to find the speed of each pedestrian, given that one pedestrian's speed is 1 km/h greater than the other.

Solution

Let's assume the speed of the slower pedestrian is x km/h. Then the speed of the faster pedestrian will be (x + 1) km/h.

To find the distance traveled by each pedestrian, we can use the formula: distance = speed × time.

For the slower pedestrian: - Distance = x km/h × 3 hours = 3x km

For the faster pedestrian: - Distance = (x + 1) km/h × 3 hours = 3(x + 1) km

Since they meet after 3 hours, the sum of their distances should be equal to the total distance between them, which is 27 km.

So, we can set up the equation: 3x + 3(x + 1) = 27.

Simplifying the equation: - 3x + 3x + 3 = 27 - 6x + 3 = 27 - 6x = 24 - x = 4

Therefore, the speed of the slower pedestrian is 4 km/h, and the speed of the faster pedestrian is 5 km/h.

Answer

The speed of the slower pedestrian is 4 km/h, and the speed of the faster pedestrian is 5 km/h.
