You can put this solution on YOUR website! Kerry commutes 60 mi per day. If she drives 30 mi/h during the morning rush and returns over the same rout at 50 mi/h, how much time does she typically spend commuting each day
------------
Time = distance/rate
Morning time: 30 mi/30 mph=1 hr
Return time: 30 mi/50 mph=(3/5) hr
Total time = 1 3/5 hr or 1 hr 36 minutes
