A man drives to town 30 miles away at a speed of 45 mph and arrives in 40 mins. on his return he takes 60 mins.
What is his average speed for the total trip?
------
Average speed = (total distance)/(total time)
----
Total distance = 60 miles
Total time = 40 min + 60 min = 1 2/3 hrs
----
Average speed = 60/(5/3) = 36 mph
