A wheel is rolling ithout slipping at 487 meters per second to the right on a level surface. the diameter of the wheel is 100 centimeters. What is the angular speed of the wheel in revolutions per minute?

Please walk me through your steps, don't just suggest a formula.
Thank you very much.

    n =ω/2•π=v/2•π•R= v/π•D =487/3.14•1=155 rev/s =9300 rev/min.
    Are you sure that v=487 m/s? Extremely fast…

    I know it IS really fast lol, but that's what is says! Thank you for your help!
