Question

с одной и той же станции в одно и то же время вышли в противоположных направлениях два поезда. скорость одного поезда 50 км/ч, а скорость другого 85 км/ч. через какое время между ними будет 540 км?РЕШИТЕ ЗАДАЧЕЙ

Answer 1

 50+85=135 км проходят оба поезда за час, тогда 540/135=4 часа  
Ответ через 4 часа расстояние составит 540 км.

Answer 2

50+85=135км\час-общая скорость 
540:135=4 час 
ответ-через 4 часа

Answer 3

Problem Analysis

We have two trains that start from the same station 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 85 km/h. We need to find out how long it will take for the two trains to be 540 km apart.

Solution

To find the time it takes for the two trains to be 540 km apart, we can use the formula:

time = distance / relative speed

The relative speed of the two trains is the sum of their speeds since they are moving in opposite directions. Therefore, the relative speed is 50 km/h + 85 km/h = 135 km/h.

Substituting the values into the formula, we get:

time = 540 km / 135 km/h

Simplifying the equation, we find:

time = 4 hours

Therefore, it will take 4 hours for the two trains to be 540 km apart.

Answer

The two trains will be 540 km apart after 4 hours.
