The plane and the helicopter are flying in the same direction. The speed of the aircraft is 700 km / h, and the speed of the helicopter is 300 km / h. Now there are 800 km between them. How long will it take for the plane to catch up with the helicopter?

To solve the problem, you first need to find the difference in speed between an airplane and a helicopter.
To do this, subtract the speed of the helicopter from the speed of the aircraft.
In this case, we will get.

700 – 300 = 400 kilometers per hour.

After that, in order to find how long it takes for the plane to catch up with the helicopter, the total distance between them, namely 800 km, should be divided by the difference in speed.
As a result, we will get.

800/400 = 2 hours.
Answer. The plane will catch up with the helicopter in 2 hours.
