Question

Самолет пролетает 3600 км за 4 часа . сколько времени понадобится самолёту чтобы пролететь такое же растояние если его скорость составляет 1-4 скорости самолёта за какое время вертолёт пролитит 3825 км если будет двигатся с такой же скоростью?

Answer 1

1. 3600/4=900 км/ч скорость самолета
2. 900/4=225 км/ч скорость вертолета
3.3600/225=16 часов понадобится вертолету, чтобы пролететь 3600 км.
4.3825/225=17 часов понадобится вертолету, чтобы пролететь 3825 км.

Answer 2

Calculating Time Needed to Travel a Certain Distance

To calculate the time needed for the plane to travel a certain distance, we can use the formula:

time = distance / speed

Given that the plane travels 3600 km in 4 hours, we can calculate its speed:

speed = distance / time

speed = 3600 km / 4 hours

speed = 900 km/h

Now, to find the time needed for the plane to travel the same distance at a speed of 1/4 of its original speed:

time = distance / speed

time = 3600 km / (900 km/h / 4)

time = 3600 km / 225 km/h

time = 16 hours

So, the plane would need 16 hours to travel the same distance at 1/4 of its original speed.

Time Needed for a Helicopter to Travel a Certain Distance

To find the time needed for the helicopter to travel 3825 km at the same speed, we can use the same formula:

time = distance / speed

Given that the speed is the same as the plane's 1/4 speed, which is 225 km/h:

time = 3825 km / 225 km/h

time = 17 hours

Therefore, the helicopter would need 17 hours to travel 3825 km at the same speed.
