Helen rode her bike to school at an average sped of 9 miles per hour. What was her speed in feet per minute? (fpm)?

First thing I would do is change your miles into feet. 1mile=5280feet. 9*5280=47520feet
Then you would change your hour into minutes. 1hour=60minutes
Since you want it in ft/min, you put your feet and divide it by your minutes to get how much it would take for one foot.
47520/60=792ft/min

for every mile there is 5280 ft and for every hour there are 60 minutes. 9*5280/60 = 792 ft/m
