Question

С одной и тойже дистанции в одно и тоже время вышли впровотиположных напровлениях два поезда скорость одного поезда 50 км в ч, а другого 84 км в ч. какое расстояние между поездами будет через 3 часа

Answer 1

1 способ:
50*3=150 км проедет 1 поезд
84*3=252 км проедет 2 поезд
150+252=402 км будет расстояние между поездами

2 способ:
50+84=134 км/ч скорость отдаления
134*3=402 км будет расстояние между поездами

Answer 2

(50+85)*3=405 км будет

Answer 3

Problem Analysis

We have two trains that start from the same distance at the same time, but in opposite directions. The speed of one train is 50 km/h, and the speed of the other train is 84 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 × Time

Let's calculate the distance traveled by each train after 3 hours and then find the total distance between them.

Train 1: - Speed: 50 km/h - Time: 3 hours - Distance = 50 km/h × 3 hours = 150 km

Train 2: - Speed: 84 km/h - Time: 3 hours - Distance = 84 km/h × 3 hours = 252 km

The total distance between the trains after 3 hours is the sum of the distances traveled by each train:

Total Distance = Distance of Train 1 + Distance of Train 2

Total Distance = 150 km + 252 km = 402 km

Therefore, the distance between the trains after 3 hours will be 402 kilometers.
