Question

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

Answer 1

1)350*4= 1400(км) пролетит со скоростью 350 км/ч
2)(350-50)*4= 1200(км) пролетит с уменьшенной скоростью
3)1400-1200=200(км)
ответ: на 200 км меньше

Answer 2

Calculation of the Distance Traveled by the Helicopter

To calculate the distance traveled by the helicopter, we need to multiply its speed by the time it flies.

Given: - Initial speed of the helicopter: 350 km/h - Time flown: 4 hours - Reduction in speed: 50 km/h

To find the distance traveled at the reduced speed, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by the helicopter at the initial speed and at the reduced speed.

1. Distance traveled at the initial speed: - Speed: 350 km/h - Time: 4 hours

Distance = 350 km/h x 4 hours = 1400 km.

2. Distance traveled at the reduced speed: - Speed: 350 km/h - 50 km/h = 300 km/h - Time: 4 hours

Distance = 300 km/h x 4 hours = 1200 km.

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