Question 1165380: one airplane pilot flew 4 hours to her destination. On her return trip she flew 120mph faster. Her total flying time was 7 hours. Find the rate of both trips Answer by ikleyn(52898) (Show Source):
The distance equation is
4x = 3*(x+120)
saying that the distance both ways is the same.
From the equation, find x, the rate going to the destination.
Then evaluate x+120, the rate going back.
