Question

Вертолёт летит со скоростью 350км/Ч.На сколько меньше километров он пролетит за 4ч,если его скорость уменьшиться на 50км/Ч?

Answer 1

350*4=1400км пролетел в первом случае
350-50=300км/ч скорость во втором случае
300*4=1200км пролетел во втором случае
1400-1200=200км разница
на 200км

Answer 2

1)350 * 4 = 1400 (км) при нынешней скорости
2)350 - 50 = 300 (км/ч) новая скорость.
3)300 * 4 = 1200 (км) при новой скорости
4)1400  - 1200 = 200 (км) разница. 
Ответ:  на 200 км. 

Answer 3

Calculating the Reduced Distance Traveled by the Helicopter

To calculate the reduced distance the helicopter will travel when its speed is decreased by 50 km/h, we can use the formula:

Distance = Speed × Time

First, let's calculate the distance the helicopter would travel at its original speed of 350 km/h in 4 hours: Distance = 350 km/h × 4 h = 1400 km.

Now, let's calculate the distance the helicopter would travel at the reduced speed of 300 km/h in 4 hours: Distance = 300 km/h × 4 h = 1200 km.

Conclusion

The helicopter would travel 200 kilometers less when its speed is reduced by 50 km/h for a 4-hour flight.
