You can put this solution on YOUR website! Michelle jogs 12 miles in one hour and 30 mins. Find speed in MPH.
Rate = distance/time
Rate = 12 mi/ (3/2) hr = 24/3 = 8 mph
============================================
What if she jogs 18 miles?
Rate = distance /time
Rate = 18 mi/ (3/2) hr = 36/3 = 12 mph
=============================================
