Question

Со станции одновременно вышли два поезда в противном направлениях скорость одного поезда 52км/ч скорость другого 48км/ч через сколько часов поезда будут находиться один от другого на расстояние 500км

Answer 1

500 : ( 52 + 48 ) = 500 : 100 = 5 ( часов )

Answer 2

500÷(52+48)=5 (ч) ответ: через 5 часов встретятся поезда

Answer 3

Problem Analysis

We have two trains that start simultaneously from the same station, but in opposite directions. The speed of one train is 52 km/h, and the speed of the other train is 48 km/h. We need to determine how many hours it will take for the trains to be 500 km apart from each other.

Solution

To solve this problem, we can use the formula: distance = speed × time. We know the distance between the trains is 500 km, and we need to find the time it takes for them to reach this distance.

Let's assume that the time it takes for the trains to be 500 km apart is t hours.

The distance covered by the first train in t hours is given by: 52 × t.

The distance covered by the second train in t hours is given by: 48 × t.

According to the problem, the sum of these distances should be equal to 500 km:

52 × t + 48 × t = 500

Simplifying the equation:

100 × t = 500

Dividing both sides of the equation by 100:

t = 5

Therefore, it will take 5 hours for the trains to be 500 km apart from each other.

Answer

The trains will be located 500 km apart from each other after 5 hours.
