 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 2{{{1/4}}} 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) </PRE>
