Question

От двух станций, расстояние иежду которыми равно 20,8 км, в одном направлении одновременно отправились два поезда.Впереди шёл поезд со скоростью 54,6 км/ч. Через 5 ч после начала движения его догнал второй поезд. Найдите скорость второго Поезда

Answer 1

V2-x
54,6*5-5x=20,8
273-5x=20,8
-5x=20,8-273
-5x=-252,2:(-5)
x=50,44

Answer 2

Problem Analysis

We are given that two trains start simultaneously from two stations that are 20.8 km apart. The first train is traveling at a speed of 54.6 km/h. After 5 hours, the second train catches up to the first train. We need to find the speed of the second train.

Solution

Let's assume the speed of the second train is x km/h.

To find the speed of the second train, we can set up the following equation based on the distance traveled by both trains:

Distance traveled by the first train = Distance traveled by the second train

The distance traveled by the first train is given by the product of its speed and the time it
