Question

Самолёт пролетает 3600 км за 4 ч.Сколько времени понадобится вертолёту,чтобы пролететь такое же расстояние если его скорость составляет 1/4 скорости самолёта? За какое время вертолёт пролетит 3825 км,если будет двигаться с той же скоростью?

Answer 1

1)3600:4=900
2)3825:4=956

Answer 2

1) Определим скорость самолета:Vсам=S/t=3600/4=900 км/час2)  Определим скорость вертолета:Vверт=(1/4)*Vсам=(1/4)*900=225 км/час3) Определим время вертолета на расстоянии 3825 км:t=S/Vверт=3825/225=17 час

Answer 3

Calculation for the Time Required for the Helicopter to Travel the Same Distance

To calculate the time required for the helicopter to travel the same distance as the airplane, we need to consider that the helicopter's speed is 1/4 of the airplane's speed.

Given that the airplane travels 3600 km in 4 hours, we can calculate the airplane's speed as follows:

Airplane speed = Distance / Time = 3600 km / 4 hours = 900 km/h

Since the helicopter's speed is 1/4 of the airplane's speed, the helicopter's speed is:

Helicopter speed = 1/4 * Airplane speed = 1/4 * 900 km/h = 225 km/h

Now, to calculate the time required for the helicopter to travel the same distance, we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time = 3600 km / 225 km/h = 16 hours

Therefore, the helicopter would take 16 hours to travel the same distance as the airplane.

Calculation for the Time Required for the Helicopter to Travel 3825 km

To calculate the time required for the helicopter to travel 3825 km at the same speed as before (225 km/h), we can use the same formula:

Time = Distance / Speed

Substituting the values, we get:

Time = 3825 km / 225 km/h = 17 hours

Therefore, the helicopter would take 17 hours to travel a distance of 3825 km at a speed of 225 km/h.

Please note that these calculations assume a constant speed throughout the entire journey and do not account for factors such as wind resistance or changes in speed during the flight.
