On the way to Boston, he drives 65 miles per hour, taking an 1-hour rest stop during the drive. After finishing his business in Boston, he make the return trip driving at 60 miles per hour and takes a 45-minute rest stop halfway through the trip. Which leg of the journey, Washington, D.C. to Boston, or Boston to Washington, D.C., takes the longer time?


Hi Ameer,

On the way to Boston he drives at 65 miles per hour and hence he spends  442/65 = 6.8 hours driving. He takes a 1 hour rest stop and hence the trip took 7.8 hours.

How long did the return trip take?
