Convert mi/hr to in/min
[ mi/hr ] x [ ft/mi ] x [ in/ft ] x [ hr/min ]
in/min
---------------------------------------
Find cicumference, , in inches
in/rev
------------------------
[ in/rev ] / [ in/min ] = [ min/rev ]
min/rev
rev/min
-----------------------------------------
[ rad / rev ] * [ rev/min ] = rad/min
rad/min
check the math
