Question

С аэродрома одновременно в противоположных направлениях вылетели вертолёт и самолёт. когда самолет пролетел 2142 км со скоростью 714 км в час Расстояние между ними стало 2832 км. с какой скоростью летел вертолет

Answer 1

1)2832-2142=690

2)2142:714=3

3)690×3=2070

Ответ:2070км

Answer 2

Calculation of Helicopter's Speed

To determine the speed of the helicopter, we can use the information provided in the question.

We know that the airplane flew a distance of 2142 km with a speed of 714 km/h. During this time, the distance between the airplane and the helicopter increased to 2832 km.

To find the speed of the helicopter, we can set up a proportion using the distances traveled by the airplane and the helicopter:

Distance traveled by airplane / Speed of airplane = Distance traveled by helicopter / Speed of helicopter

Substituting the given values:

2142 km / 714 km/h = 2832 km / Speed of helicopter

Simplifying the equation:

3 = 2832 km / Speed of helicopter

To find the speed of the helicopter, we can cross-multiply and solve for the unknown variable:

Speed of helicopter = 2832 km / 3

Calculating the speed of the helicopter:

Speed of helicopter = 944 km/h

Therefore, the helicopter was flying at a speed of 944 km/h.
