the wheel ( including the tire) of a sports car under development by one of the Big Three auto companies has an 11 in radius. what would be the car's speed in miles per hour if its wheel are turning 800 rpm?

-------------------

800 rev/ 1 min x 60 min/ 1 hr x 2 pi radians/ 1 revolution x 11 in / 1 radian x 1 ft/ 12 in x 1 mi/ 5280 ft

= 52.36ft

Did I do this correctly?
