Question

От одной станции одновременно в противоположность направлениях вышли два поезда,один из которых шёл со скоростью 62 км/ч.через 5 часов расстояние между ними было 630 км.чему равна скорость второго поезда?

Answer 1

5•62=310км прошел один поезд
(630-310):5=64км/ч скорость второго поезда

Answer 2

Calculation of the Second Train's Speed

To calculate the speed of the second train, we can use the formula: speed = distance / time.

Given that the distance between the two trains after 5 hours is 630 km, we can use this information to calculate the speed of the second train.

Let's denote the speed of the first train as v1 and the speed of the second train as v2.

We know that the first train is traveling at a speed of 62 km/h. After 5 hours, the first train would have covered a distance of 62 km/h * 5 h = 310 km.

Therefore, the remaining distance between the two trains is 630 km - 310 km = 320 km.

Using the formula mentioned earlier, we can calculate the speed of the second train:

v2 = distance / time = 320 km / 5 h = 64 km/h.

Therefore, the speed of the second train is 64 km/h.
