The Cedar Bluff express KAT bus averages 5 mph for 17 minutes, and then 44 mph for 13 minutes. What was its average speed? (mph)

Calculate the total distance driven and divide it by 1/2 hour (30 minutes).
You will need to convert mph speeds to miles/minute when multiplying by travel times in mintes.
5 mph is 1/12 miles/minute
44 mph is 11/15 miles/minute
