Question

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

Answer 1

1)350*4=1400 км пролетает вертолёт за 4 часа.
2)350-50=300 км/ч уменьшенная скорость вертолёта
3)300*4=1200 км пролетает теперь вертолёт за 4 часа 
4)1400-1200=200 км
Ответ:на 200 км меньше 

Answer 2

S=Vt
350 км/ч*4 ч=1400 км (пролетит со скоростью 350 км/ч)
350 км/ч-50 км/ч=300 км/ч (уменьшенная скорость)
300 км/ч*4 ч=1200 км
1400 км-1200 км=200 км
Ответ: вертолет пролетит на 200 км меньше

Или:
S=Vt
50 км/ч*4 ч=200 км
Ответ: вертолет пролетит меньше на 200 км

Answer 3

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 - Decrease in speed: 50 km/h

To find the distance traveled when the speed is reduced by 50 km/h, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by the helicopter when its speed is reduced by 50 km/h.

Step 1: Calculate the distance traveled at the initial speed of 350 km/h.

Distance1 = 350 km/h x 4 hours

Step 2: Calculate the distance traveled when the speed is reduced by 50 km/h.

New speed = 350 km/h - 50 km/h = 300 km/h

Distance2 = 300 km/h x 4 hours

Calculation Results

The distance traveled by the helicopter at the initial speed of 350 km/h is 1400 kilometers.

The distance traveled by the helicopter when its speed is reduced by 50 km/h to 300 km/h is 1200 kilometers.

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