Question 315046: the Jones family drove to their parents' house at 45km/h. The return trip yook 1 hour less because they traveled at 60km/h. How long did it take them to get home? Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Going:
rate = 45km per hour
time = x
distance = 45x
Returning:
rate = 60km per hour
time = x - 1
distance = 60(x - 1)
