Question

ОттОт одной станции одновременно отошли в противоположных направлениях два электоропоезда. Скорость одного 55км\ч а другой 60км\ч. Какое расстояние будет между поездами через 3 часов?

Answer 1

1) 55 + 60 = 115 (  км/час ) скорость удаления 
2) 3 * 115 = 345 (  км )
ОТВЕТ 345 км

Answer 2

55+60=115 км/ч общая скорость отдаления
115*3=345 км расстояние через 3 часа

Answer 3

Calculation of the Distance between the Trains

To calculate the distance between the two trains after 3 hours, we need to consider their speeds and the time elapsed.

Let's denote the speed of the first train as 55 km/h and the speed of the second train as 60 km/h. Since the trains are moving in opposite directions, their relative speed is the sum of their individual speeds.

The relative speed of the trains is 55 km/h + 60 km/h = 115 km/h.

To find the distance between the trains after 3 hours, we can use the formula:

Distance = Speed × Time

Plugging in the values, we get:

Distance = 115 km/h × 3 hours = 345 km

Therefore, the distance between the two trains after 3 hours will be 345 kilometers.
