A plane and a helicopter departed from one airfield simultaneously in opposite directions. The speed of the aircraft is 740 km / h, and the speed of the helicopter is 260 km / h. in how many minutes the distance between the plane and the helicopter will be 13000 km.

1. Let’s find at what speed the plane and the helicopter move away from each other:

740 + 260 = 1000 (km / h).

2. Let’s find after what time the distance between the plane and the helicopter will be 13000 km:

13000: 1000 = 13 (hour).

13 hours = 780 minutes.

Answer: in 780 minutes the distance between the plane and the helicopter will be 13,000 km.
