a car's linear velocity is 7.85m/s since it was moving around a track of diameter 50m and had a period of 20s, what would the angular velocity be?

A)0.314 rad/s
B)196.25 rad/s
C)7.85 rad/s
D)9.8 rad/s
 
Don't know how to solve this problem. All I know is that you have your radius = 25 m, the time = 20s and its velocity = 7.85 m/s other than I can't help out from what I don't know too well
