Question

Помогите пж даю 100 баллов Задача: 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 расположения между ними будет ровно 540 км?

Answer 1

Ответ: Через 4 часа

1) 85 + 50 = 135км/ч

2 540/135 = 4ч

Answer 2

1)50+85=135 2) 540:135=4 Ответ:через 4 часа

Answer 3

Problem Analysis

We have two trains leaving the same station at the same time 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 determine how long it will take for the distance between them to be exactly 540 km.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for each train to travel a distance of 540 km.

For the first train with a speed of 50 km/h: time1 = 540 km / 50 km/h

For the second train with a speed of 85 km/h: time2 = 540 km / 85 km/h

Now, let's calculate the values:

time1 = 540 km / 50 km/h = 10.8 hours

time2 = 540 km / 85 km/h = 6.35 hours

Therefore, the time it takes for the distance between the two trains to be exactly 540 km is approximately 10.8 hours or 6 hours and 21 minutes.

Note: The exact time will depend on the decimal places considered.

I hope this helps! Let me know if you have any further questions.
