Question

Из двух городов расстояние между которыми500 км вышли навстречу друг другу два поезда Скорость одного поезда 45 км ч Определите скорость второго поезда если если поезда встретятся через 5 часов

Answer 1

Problem Analysis

We have two trains traveling towards each other from two different cities. The distance between the cities is 500 km. We know the speed of one train is 45 km/h, and we need to determine the speed of the second train. The trains will meet after 5 hours.

Solution

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

Distance = Speed × Time

Since the trains are moving towards each other, the total distance covered by both trains is equal to the distance between the cities, which is 500 km. Let's assume the speed of the second train is x km/h.

For the first train: Distance = Speed × Time Distance = 45 km/h × 5 hours Distance = 225 km

For the second train: Distance = Speed × Time 500 km - 225 km = x km/h × 5 hours 275 km = 5x km/h

To find the speed of the second train, we can divide both sides of the equation by 5:

275 km / 5 hours = 5x km/h / 5 hours 55 km/h = x km/h

Therefore, the speed of the second train is 55 km/h.

Answer

The speed of the second train is 55 km/h.
