Question

Один из двух поездов, двигающихся с одинаковой скоростью, был в пути 7 часов, а другой - 4 часа. Найдите скорости поездов, если второй поезд проехал на 222 км меньше, чем первый.

Answer 1

Problem Analysis

We are given two trains that are traveling at the same speed. One train takes 7 hours to reach its destination, while the other train takes 4 hours. The second train travels 222 km less than the first train. We need to find the speeds of both trains.

Solution

Let's assume the speed of both trains is x km/h.

The distance traveled by the first train can be calculated as 7x km. The distance traveled by the second train can be calculated as 4x km.

According to the given information, the second train traveled 222 km less than the first train. Therefore, we can write the equation:

7x - 4x = 222

Simplifying the equation, we get:

3x = 222

Solving for x, we find:

x = 74

So, the speed of both trains is 74 km/h.

Answer

The speed of both trains is 74 km/h.
