Question

Из двух городов расстояние между которыми 846 км вышли одновременно навстречу друг другу два поезда.Скорость одного поезда 48 км в час а другого 56 км в час.Какое расстояние будет между поездами через 3 часа

Answer 1

1) 56*3=168(км)-проехал первый поезд
2) 48*3=144(км)-проехал второй поезд
3) 168+144=312(км)-проехали два поезда вместе
4) 846-312=534(км)-расстояние между поездами
Ответ:534 км.

Answer 2

846-(48×3)+(56×3)=534

Answer 3

Problem Analysis

We are given that two trains start simultaneously from two cities that are 846 km apart and are moving towards each other. 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 can use the formula:

Distance = (Speed of Train 1 + Speed of Train 2) × Time

Let's substitute the given values into the formula and calculate the distance.

Speed of Train 1 = 48 km/h

Speed of Train 2 = 56 km/h

Time = 3 hours

Distance = (48 + 56) × 3

Distance = 104 × 3

Distance = 312 km

Therefore, the distance between the trains after 3 hours will be 312 km.

Answer

The distance between the two trains after 3 hours will be 312 km.
