Question

С аэродрома вылетели в противоположных направлениях 2 самолёта . через 3 часа расстояние между ними было 3630 км .Скорость первого самолёта 640 км/ч .Какое расстояние второго самолёта ?

Answer 1

640 *3=1920(км ) пролетел 1 первый самолет за три часа
3630-1920=1710(км пролетел 2 самолет за три часа
1710/3=570(км/ч) скорость 2 самолета
ответ : скорость 2 самолета 570 км/ч

Answer 2

640 * 3 = 1920
3630 - 1920 = 1710
1710 : 3 = 570

Answer 3

Calculation of the Distance of the Second Plane

To calculate the distance of the second plane, we can use the formula:

Distance = Speed x Time

Given that the speed of the first plane is 640 km/h and the time elapsed is 3 hours, we can calculate the distance traveled by the first plane:

Distance of the first plane = 640 km/h x 3 hours = 1920 km.

Since the total distance between the two planes is 3630 km, we can subtract the distance traveled by the first plane from the total distance to find the distance of the second plane:

Distance of the second plane = Total distance - Distance of the first plane = 3630 km - 1920 km = 1710 km.

Therefore, the distance of the second plane is 1710 km.
