John gets lost on his way home.  His normal trip is 150 miles and would take him 3 hours.  He ends up driving 50 miles out of the way and has to get back on track.  How long did the trip take if he kept the same speed?
How fast does John drive? ** His speed is 150/3=<<150/3=50>>50 mph
How many miles was John detoured? ** He was detoured 50*2=<<50*2=100>>100 miles
How many hours did John add? ** So that adds 100/50=<<100/50=2>>2 hours
How long did the trip take? ** So the total trip was 3+2=<<3+2=5>>5 hours
