Question

Со станции одновременно в противоположных направлениях отправились два поезда.один ехал со скоростью 72км/ч,а другой 70км/ч.какое расстояние было между ними,когда второй поезд проехал 210км?

Answer 1

1)72*70=5040(км)-все ихнее  расстояние

2)5040/210=24(км)

Ответ.Расстояние между ними было 24 километра.

Answer 2

210/70=3 часа двигались поезда
72*3=216 км проехал первый поезд
210+216=426 км

Answer 3

Calculation of the Distance between Two Trains

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

Distance = Speed x Time

In this case, we know that the second train traveled a distance of 210 km. We also know the speeds of both trains: one is traveling at 72 km/h, and the other is traveling at 70 km/h.

Let's calculate the time it took for the second train to travel 210 km:

Time = Distance / Speed

For the second train: Time = 210 km / 70 km/h = 3 hours

Now that we know the time it took for the second train to travel 210 km, we can calculate the distance between the two trains when the second train reached that point.

For the first train: Distance = Speed x Time Distance = 72 km/h x 3 hours = 216 km

Therefore, when the second train traveled 210 km, the distance between the two trains was 216 km.
