Question

Из двух городов расстояние между которыми 846км вышли одновременно два поезда.скорость одного поезда 48км/ч,а скорость другого 56км/ч.какое расстояние будет между поездами через 3ч.?

Answer 1

48+56=94км/я преодолевает оба поезда
94×3=282 км за 3 часа
846-282=564 км

Answer 2

Problem Analysis

We are given that two trains start simultaneously from two cities that are 846 km apart. The speed of one train is 48 km/h, and the speed of the other train is 56 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 distance traveled by each train in 3 hours and then find the difference between the two distances.

Let's calculate the distance traveled by each train:

- Train 1: Speed = 48 km/h, Time = 3 hours Distance traveled by Train 1 = Speed * Time = 48 km/h * 3 hours = 144 km

- Train 2: Speed = 56 km/h, Time = 3 hours Distance traveled by Train 2 = Speed * Time = 56 km/h * 3 hours = 168 km

Now, let's find the difference between the distances traveled by the two trains:

Distance between the trains = Distance traveled by Train 2 - Distance traveled by Train 1 = 168 km - 144 km = 24 km

Therefore, the distance between the trains after 3 hours is 24 km.

Answer

The distance between the trains after 3 hours will be 24 km.
