Question

С двух станций расстояние между которыми равно 240 км одновременно в одном направлении отправились два поезда впереди двигался поезд со скоростью 58 километров час через 4 часа после начала движения его догнал второй поезд Найдите скорость второго поезда

Answer 1

58*4=232км = проехал 1 поезд
240+232=472км- проехал 2 поезд
472:4=118км/ч - скорость 2 поезда

Problem Analysis

We are given that two trains start simultaneously from two stations that are 240 km apart. The first train is moving at a speed of 58 km/h, and after 4 hours of starting its journey, it is overtaken by the second 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 use the formula:

Distance = Speed × Time

For the first train: Distance covered by the first train = Speed of the first train × Time Distance covered by the first train = 58 km/h × 4 hours Distance covered by the first train = 232 km

Since the second train overtakes the first train, the distance covered by the second train is the total distance between the two stations (240 km) minus the distance covered by the first train (232 km).

Distance covered by the second train = Total distance - Distance covered by the first train Distance covered by the second train = 240 km - 232 km Distance covered by the second train = 8 km

Now, we can use the formula to find the speed of the second train:

Speed of the second train = Distance covered by the second train ÷ Time Speed of the second train = 8 km ÷ 4 hours Speed of the second train = 2 km/h

Therefore, the speed of the second train is 2 km/h.

Answer

The speed of the second train is 2 km/h.
