Question

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

Answer 1

1)350*4=1400(км)
2)350-50=300(км.в час)
3)300*4=1200(км)
4)1400-1200=200(км)
Ответ:пролетит на 200 км. меньше.

Answer 2

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 the time is 4 hours, we can calculate the initial distance traveled using the formula:

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. Using the same formula as above, we can calculate the reduced distance:

Reduced Distance = 300 km/h × 4 hours

To find the difference between the initial distance and the reduced distance, we subtract the reduced distance from the initial distance:

Difference = 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 = 1400 km - 1200 km = 200 km.

Therefore, if the speed of the helicopter is reduced by 50 km/h, it will travel 200 km less in 4 hours compared to its initial speed of 350 km/h.
