Question

От станций одновременно в противоположных направлениях отошли два поезда.Скорость одного из них 86 км.ч а скорость второго-70 км.ч.Сколько киллометров пути будет между поездами через 5 ч.

Answer 1

Между поездами будет расстояние 780 км.
1).86+70=156(км)
2).156*5=780(км)

Answer 2

Calculation of Distance between Trains

To calculate the distance between two trains that departed simultaneously in opposite directions, we can use the formula:

Distance = (Speed of Train 1 + Speed of Train 2) * Time

Given that the speed of Train 1 is 86 km/h and the speed of Train 2 is 70 km/h, and the time elapsed is 5 hours, we can substitute these values into the formula:

Distance = (86 km/h + 70 km/h) * 5 hours

Calculating the distance:

Distance = (156 km/h) * 5 hours

Distance = 780 km

Therefore, the distance between the two trains after 5 hours will be 780 kilometers.
