Problema Solution
On his way home to work, your uncle averaged only 20 miles per hour. On his drive home, he averaged 40 miles per hour. If the total travel time 1.5 hours, how long did it take him to drive to work?
Answer provided by our tutors
Let T be the time take him to drive to work. Then (1.5-T) is the time of his drive home.
20T=40(1.5-T)
20T=60-40T.
60T=60.
T=60/60.
=1 H.
