The first helicopter flew 480 km, and the second-800 km. The first helicopter was in flight 2 hours less than the second.

The first helicopter flew 480 km, and the second-800 km. The first helicopter was in flight 2 hours less than the second. How many hours did each helicopter fly if their speeds were the same?

1. Find how many fewer kilometers the first helicopter flew than the second.
800 – 480 = 320 kilometers.
2. Find out with what speed the helicopter flew if it is known that in 2 hours it flew 320 kilometers.
320/2 = 160 kilometers.
3. Find how many hours the first plane was in the air if it is known that it flew 480 kilometers.
480/160 = 3 hours.
4. Let’s determine how many hours the second helicopter was in flight.
800/160 = 5 hours.
Answer: The first helicopter was in flight for three hours, and the second for five hours.
