Question

С одной станции выехал поезд со скоростью75км/ч. Через 2 часа с той же станции в противоположном направлении выехал другой поезд со скоростью 64км/ч .Какое расстояние будет между поездами через 3 часа после отправления первого поезда? через3 часа после отправления второго поезда ???

Answer 1

75*2=150км прошёл 1поезд
150+75+64=289км будет ч/з 3ч после отправления 1поезда
(64+75)*2+289=567 км будет ч/з 3ч после отправления 2поезда

Answer 2

Calculation of Distance between Trains

To calculate the distance between the two trains after 3 hours, we need to consider the distances covered by each train individually.

Train 1: - Speed: 75 km/h - Time: 3 hours

The distance covered by Train 1 can be calculated using the formula: distance = speed * time. So, the distance covered by Train 1 after 3 hours is 75 km/h * 3 hours = 225 km.

Train 2: - Speed: 64 km/h - Time: 3 hours

Similarly, the distance covered by Train 2 after 3 hours is 64 km/h * 3 hours = 192 km.

Therefore, the distance between the two trains after 3 hours since the departure of the first train is the sum of the distances covered by each train: 225 km + 192 km = 417 km.

Please note that these calculations assume that the trains are traveling in opposite directions from the same station.
