Question 801508: The wheels on a certain bicycle have a radius of 13.2 inches. Suppose the wheels roll at 150 revolutions per minute along flat ground without slipping. How fast is the bicycle moving in miles per hour?
The question then hints to convert revolutions to radians per minute, but I am unsure how to do this and any help on what to do to get the answer would be greatly appreciated! Thank you!

***
Use dimensional analysis method
rev=revolution
r=radius of wheel=13.2 inches
circumference of wheel=2*π*r
..

rev,min,inches,ft cancel out, leaving:
