Question

В18ч с двух станций навстречу друг другу выехали два пассажирских поезда.Они встретились в23ч того же дня.Какое расстояние между станциями,если скорость одного поезда-70км\ч,а другого-90км\ч?

Answer 1

1)70+90=160(км/ч)-общая скорость.
2)23-18=5(ч)-встретятся.
3)160×5=800(км)-расстояние.
Ответ:800 км расстояние между станциями.

Answer 2

Calculation of the Distance Between Stations

To calculate the distance between the two stations, we can use the formula:

Distance = Speed x Time

Let's calculate the time it took for the two trains to meet first.

Given: - Train 1's speed = 70 km/h - Train 2's speed = 90 km/h

We know that the two trains started at 18:00 and met at 23:00 on the same day. Therefore, the time it took for them to meet is 5 hours.

Now, let's calculate the distance between the two stations using the formula mentioned above.

For Train 1: Distance1 = Speed1 x Time = 70 km/h x 5 h = 350 km

For Train 2: Distance2 = Speed2 x Time = 90 km/h x 5 h = 450 km

Therefore, the distance between the two stations is 350 km.
