Question

С одной и тойже станции в одно и тоже время вышли в противоположных направлениях 2 поезда. скорость одного поезда=50км/ч другого=85км/ч. какое растояние будет между поездами через 3 ч? РЕШИТЕ С КРАТКОЙ ЗАПИСЬЮ ПОЖАЛУСТО

Answer 1

S=U*t
50*3=150 км(расстояние, которое прошёл первый поезд)
85*3=255км(расстояние, которое прошел второй  поезд)
150+255=405км(расстояние между ними)

Answer 2

Problem Analysis

We have two trains that start from the same station in opposite directions at the same time. The speed of one train is 50 km/h, and the speed of the other train is 85 km/h. We need to find the distance between the trains after 3 hours.

Solution

To find the distance between the trains after 3 hours, we need to calculate the total distance traveled by each train.

Let's calculate the distance traveled by the first train: Distance = Speed × Time Distance = 50 km/h × 3 h Distance = 150 km

Now let's calculate the distance traveled by the second train: Distance = Speed × Time Distance = 85 km/h × 3 h Distance = 255 km

The distance between the trains after 3 hours is the sum of the distances traveled by each train: Total Distance = Distance of First Train + Distance of Second Train Total Distance = 150 km + 255 km Total Distance = 405 km

Therefore, the distance between the trains after 3 hours is 405 km.

Answer

The distance between the two trains after 3 hours will be 405 km.
