Question

с двух станций одновременно навстречу друг другу вышли два поезда. один поезд проходит 65км, а другой 72 км в час. через 8 часов они встретились. какое растояние между станциями? какое расстояноие было между поездами через 6 часов после начала движения

Answer 1

1)65+72=137км-скорость сближения.

2)137*8=1096км-расстояние между станциями.

3)137*6=822км-проехали вместе за 6ч.

4)1096-822=274км-было между ними через 6 ч.

Answer 2

Given Information:

- Two trains start simultaneously from two different stations and travel towards each other. - The first train travels at a speed of 65 km/h. - The second train travels at a speed of 72 km/h. - After 8 hours, the trains meet each other.

Calculating the Distance between the Stations:

To calculate the distance between the stations, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by each train after 8 hours: - The first train travels at a speed of 65 km/h for 8 hours, so the distance covered by the first train is 65 km/h × 8 h = 520 km. - The second train travels at a speed of 72 km/h for 8 hours, so the distance covered by the second train is 72 km/h × 8 h = 576 km.

To find the total distance between the stations, we can add the distances covered by each train: - Total distance = distance covered by the first train + distance covered by the second train - Total distance = 520 km + 576 km - Total distance = 1096 km

Therefore, the distance between the stations is 1096 km.

Calculating the Distance between the Trains after 6 Hours:

To calculate the distance between the trains after 6 hours, we need to find the distance covered by each train in that time.

Let's calculate the distance traveled by each train after 6 hours: - The first train travels at a speed of 65 km/h for 6 hours, so the distance covered by the first train is 65 km/h × 6 h = 390 km. - The second train travels at a speed of 72 km/h for 6 hours, so the distance covered by the second train is 72 km/h × 6 h = 432 km.

To find the distance between the trains, we can subtract the distance covered by the first train from the total distance between the stations: - Distance between the trains = total distance - distance covered by the first train - Distance between the trains = 1096 km - 390 km - Distance between the trains = 706 km

Therefore, the distance between the trains after 6 hours is 706 km.

Conclusion:

- The distance between the stations is 1096 km. - The distance between the trains after 6 hours is 706 km.
