Because of traffic conditions, he averages 22 mph.
He returns home averaging 32 mph.
The total travel time is 2 1/4 hours.
Write the equation to find the time Juan spends driving to work.
:
Change 21%2F4 hrs to 2.25 hrs
:
Let t = His time to work
then
(2.25-t) = His time from work
:
Distance and to and from is equal. Write a distance equation and find t
22t = 32(2.25-t)
