Question

С одного аэродрома одновременно в противоположных направлениях вылетели два самолета. Отдин летел со скоростью 420 километров в час, скорость другого на 8 километров в час меньше. какое расстояние между ними будет через 3 часа?

Answer 1

1)420-8=412(км/ч)-скорость второго.
2)412+420=832(км/ч)-скорость удаления.
3)832*3=2496(км)
Ответ:через 3 часа расстояние между самолетами будет 2496 км.

Удачи!:)

Answer 2

Calculation of the Distance between Two Planes

To calculate the distance between two planes that took off simultaneously from the same airport in opposite directions, we need to consider their speeds and the time that has passed.

Let's denote the speed of the first plane as 420 km/h and the speed of the second plane as (420 - 8) km/h (since the second plane's speed is 8 km/h less than the first plane).

The distance traveled by each plane after 3 hours can be calculated using the formula:

Distance = Speed × Time

For the first plane: Distance1 = 420 km/h × 3 hours

For the second plane: Distance2 = (420 - 8) km/h × 3 hours

To find the distance between the two planes, we subtract the distance traveled by the second plane from the distance traveled by the first plane:

Distance between the planes = Distance1 - Distance2

Let's calculate the distances and find the final answer.
