An airplane flies 3600 km in 4 hours. How long does it take for a helicopter to fly the same distance if its speed is one-fourth the speed of the airplane? How long does it take for a helicopter to fly 3825 km if it moves at the same speed?

1. Let’s find at what speed the plane flies per hour, if it is known that it flew 3600 kilometers in 4 hours.
3600/4 = 900 kilometers.
2. Let us determine the speed of the helicopter if it is known that it is 4 times less than the speed of the aircraft.
900/4 = 225 kilometers.
3. Find out in how many hours the helicopter will fly the distance of 3600 kilometers.
3600/225 = 16 hours.
4. Let’s determine the time for which the helicopter will fly 3825 kilometers.
3825/225 = 17 hours.
Answer: The helicopter will fly 3600 kilometers in 16 hours, and 3825 kilometers in 17 hours.
