You can put this solution on YOUR website! Jenna ran 2 miles in 12 minutes. How fast was jenna running in miles per hours?
----------
12 mins = 1/5 hours
d = r*t
r = d/t = 2 mi/(0.2) hr
r = 10 mi/hr
============
Or,
r = 2/12 mi/min * 60 min/hr = 120/12 mi/hr (notice how the units cancel if you do it right)
= 10 mi/hr
Whichever you prefer
