Question

Вертолет летит со скоростью 350 км\ч . на сколько меньше километров он пролетит за 4 ч если его скорость уменьшится на 50 км\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

Calculation of Distance Traveled

To calculate the distance traveled by the helicopter, we can use the formula:

Distance = Speed × Time

Given that the initial speed of the helicopter is 350 km/h and it flies for 4 hours, we can calculate the initial distance traveled:

Initial Distance = 350 km/h × 4 hours

Now, we need to calculate the distance traveled when the speed of the helicopter is reduced by 50 km/h. Let's denote the reduced speed as 350 km/h - 50 km/h = 300 km/h.

Reduced Distance = 300 km/h × 4 hours

To find the difference in distance traveled, we subtract the reduced distance from the initial distance:

Difference in Distance = Initial Distance - Reduced Distance

Let's calculate the values:

Initial Distance = 350 km/h × 4 hours = 1400 km Reduced Distance = 300 km/h × 4 hours = 1200 km Difference in Distance = 1400 km - 1200 km = 200 km

Therefore, the helicopter will travel 200 kilometers less when its speed is reduced by 50 km/h and it flies for 4 hours.

Please note that the above calculations assume a constant speed throughout the entire flight. In reality, the speed of a helicopter may vary during different stages of the flight, so these calculations provide an approximation.
