You can put this solution on YOUR website! On a trip a student drove 40 mph for 2 hours and then drove 30 mph for 3 hours what is the average rate in mph for the whole trip
-----
40 mph for 2 hrs = 80 miles
30 mph for 3 hrs = 90 miles
----
Average rate = (total distance)/(total time) = 170 miles/5 hrs = 34 mph
