Question

Из городов М и А, расстояние между которыми равно 40 км, вышли одновременно навстречу друг к другу два лыжника. Скорость одного из них была на 2 км/ч больше скорости другого. Через 2 часа лыжники оказались на расстоянии 8 км друг от друга. С какой скоростью шел каждый лыжник?

Answer 1

Пробуйте так, если 40:2=20 Потом 8*2=16 А уже подводят итог 20-16=4км/ч шли 2 лыжника

Answer 2

Problem Setup

Two skiers, A and M, start from their respective cities and move towards each other. The distance between the cities is 40 km. After 2 hours, they are 8 km apart. One skier's speed is 2 km/h greater than the other. We need to find the speed of each skier.

Solution

Let's denote the speed of the slower skier as x km/h. Then the speed of the faster skier would be (x + 2) km/h.

Calculating the Distance

In 2 hours, the combined distance covered by both skiers is 2x + 2(x + 2) = 40 - 8.

Solving for x

Solving the equation 2x + 2(x + 2) = 32 will give us the speed of the slower skier.

Calculation

2x + 2(x + 2) = 32 2x + 2x + 4 = 32 4x + 4 = 32 4x = 32 - 4 4x = 28 x = 28 / 4 x = 7

Finding the Speed of Each Skier

The speed of the slower skier is 7 km/h, and the speed of the faster skier is 7 + 2 = 9 km/h.

So, the slower skier's speed is 7 km/h and the faster skier's speed is 9 km/h.
