Question

От станции отошёл поезд и поехал со скоростью 160 км/ч. Через 4 часа с той же станции в противоположном направлении отправился другой поезд со скоростью 172 км/ч. Какое расстояние будет между поездами через 6 часов после выхода второго поезда

Answer 1

1) 160*(4+6)=1600 км
2) 172*6=1032 км
3) 1600+1032=2632 км
Ответ:2632

Answer 2

Calculation of the Distance Between the Trains

To calculate the distance between the two trains after 6 hours, we need to determine the distance each train has traveled in that time.

The first train travels at a speed of 160 km/h for 4 hours. Therefore, the distance traveled by the first train is:

Distance of the first train = Speed of the first train × Time of travel of the first train

Distance of the first train = 160 km/h × 4 hours

To calculate the distance traveled by the second train, we need to consider that it has been traveling for 6 hours in total. However, the first train has already been traveling for 4 hours, so the second train has only been traveling for 2 hours.

The second train travels at a speed of 172 km/h for 2 hours. Therefore, the distance traveled by the second train is:

Distance of the second train = Speed of the second train × Time of travel of the second train

Distance of the second train = 172 km/h × 2 hours

Now, we can calculate the total distance between the two trains after 6 hours by subtracting the distance traveled by the second train from the distance traveled by the first train:

Total distance between the trains after 6 hours = Distance of the first train - Distance of the second train

Let's calculate the distances:

Distance of the first train = 160 km/h × 4 hours = 640 km

Distance of the second train = 172 km/h × 2 hours = 344 km

Total distance between the trains after 6 hours = 640 km - 344 km = 296 km

Therefore, the distance between the two trains after 6 hours will be 296 km.
