Question

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

Answer 1

50+75=125 км/ч скорость отдаления
125*6=750 км будет если бы они выехали из одного населенного пункта
750+275=1025 км будет между поездами после 6-ти часов отдаления.
ответ: 1025 км.

Answer 2

Problem Analysis

We have two trains, Train A and Train B, starting from cities A and B respectively, which are 275 km apart. The trains start simultaneously in opposite directions. Train A has a speed of 50 km/h, while Train B has a speed of 75 km/h. We need to find 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 covered by both trains in 6 hours.

Train A travels at a speed of 50 km/h for 6 hours, so the distance covered by Train A is: Distance covered by Train A = Speed of Train A * Time = 50 km/h * 6 hours = 300 km

Train B travels at a speed of 75 km/h for 6 hours, so the distance covered by Train B is: Distance covered by Train B = Speed of Train B * Time = 75 km/h * 6 hours = 450 km

Since the trains are moving in opposite directions, the distance between them is the sum of the distances covered by both trains: Distance between the trains = Distance covered by Train A + Distance covered by Train 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 of travel.
