A truck with 22-in.-diameter wheels is traveling at 50 mi/h.
-----
convert mi/hr to inches/minute.
-----------
50 mi/hr = ??? in/min
1 mile = 63660 inches
1 hour = 60 minutes.
----------------
1.Find the angular speed of the wheels in rad/min
A rotation of 1 radian = r = 11 inches.
---------
2.How many revolutions per minute do the wheels make?
Each revolution is 22pi inches
