From the airfield, two planes took off simultaneously and flew in opposite directions.

From the airfield, two planes took off simultaneously and flew in opposite directions. The speed of each aircraft is 850 km / h. At what distance will the planes be from each other in 3 hours of flight.

1.Calculate how far each plane will fly in 3 hours by multiplying the speed of the planes by the time:
850 km / h * 3 h = 2550 km.
2. We got that in 3 hours each of the planes will move 2550 km from each other. Then we will increase this distance by 2 times and get the distance that will become between the planes in 3 hours:
2550 km * 2 = 5100 km.
Answer: in 3 hours the distance between the two planes will be 5100 kilometers.
