Question 900939: Two planes leave at the same time one flies west at 300 km per hour. The other flies east at 450 km per hour. In how many hours will they be 2 250 kilometers apart? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! They're flying directly opposite each other.
Each hour, they are 450 + 300 km further apart.
2,250 / 750 = 3
In 3 hours, they'll be 2,250 km apart.
