Question

Из городов А и В ,находящихся на расстояние 275 км друг от друга ,вышли одновременно в противоположных направлениях два поезда .Один из них шёл со скоростью 50 км \ч,другой -со скоростью 75 км \ч .На каком расстояние друг от друга будут эти поезда через 6 ч после начала движения .

Answer 1

Problem Analysis

We have two trains, A and B, that start simultaneously from cities A and B, respectively, which are 275 km apart. Train A travels at a speed of 50 km/h, while train B travels at a speed of 75 km/h. We need to determine the distance between the two trains after 6 hours.

Solution

To find the distance between the two trains after 6 hours, we need to calculate the total distance traveled by each train.

Train A travels at a speed of 50 km/h for 6 hours, so the distance traveled by train A is:

Distance A = Speed A × Time = 50 km/h × 6 h = 300 km.

Train B travels at a speed of 75 km/h for 6 hours, so the distance traveled by train B is:

Distance B = Speed B × Time = 75 km/h × 6 h = 450 km.

Since the trains are moving in opposite directions, the distance between them is the sum of the distances traveled by each train:

Distance between the trains = Distance A + Distance B = 300 km + 450 km = 750 km.

Therefore, after 6 hours, the two trains will be 750 km apart from each other.

Answer

The two trains will be 750 km apart from each other after 6 hours.
