Question 48790: A plane took 1 hour longer to travel 560 miles on the first portion of a flight than it took to fly 480 miles on the second portion. If the speed was the same for each portion, what was the flying time for the second part of the trip? Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! let x be the speed of the plane
EQUATION
560x-480x=(x)(x)
x=0 or x = 80
Hence, the speed is 80mph.
TIme for second part of the trip:
480/80=6hours
