Question 366160: Juan drives to work. Because of traffic conditions, he averages 22 miles per hour. He returns home averaging 32 miles per hour. The total travel time is 2 1/4 hours.
a) define variable for the time Juan takes to travel to work. Write an expression for the time Juan takes to return home.
b) write and solve an equation to find the time Juan spends driving to work. Answer by ewatrrr(24785) (Show Source):
Hi,
Let x represent time spent traveling to work
then (2.25hr - x) would be time remaining to travel home
distance the same both ways. d = r*t
22x = 32(2.25hr - x)
22x = 32*2.25hrh - 32x
54x = 32*2.25hr
x = 32*2.25/54 hr
x = 1 1/3 hr, the time spent traveling to work
checking our answer
22*(4/3) = 32*11/12 = 88/3
