Question

Сомолёт и вертолёт вылетели одновременно из одного пункта и летят в одном направление кокое растояние будет между ними через 2 часа если скорость сомолёта 710б км\ч а скорость вертолёта 290 км\ч

Answer 1

1)710*2=1420
2)290*2=580
3)1420-580=840
ответ 840км

Answer 2

710-290=420 (км) будет между ними через час 
420*2=840 (км)

Answer 3

Calculation of Distance between the Plane and Helicopter

To calculate the distance between the plane and the helicopter after 2 hours, we need to consider their speeds and the time elapsed.

Given: - Speed of the plane: 710 km/h - Speed of the helicopter: 290 km/h - Time elapsed: 2 hours

To find the distance between them, we can use the formula:

Distance = Speed × Time

For the plane: Distance covered by the plane = Speed of the plane × Time elapsed

For the helicopter: Distance covered by the helicopter = Speed of the helicopter × Time elapsed

Let's calculate the distances:

Distance covered by the plane = 710 km/h × 2 hours = 1420 km

Distance covered by the helicopter = 290 km/h × 2 hours = 580 km

Therefore, the distance between the plane and the helicopter after 2 hours will be 1420 km - 580 km = 840 km.

Please note that this calculation assumes that the plane and the helicopter are flying in a straight line and at a constant speed.
