angular velocity

Hi
I need to find the angular velocity for a car moving at 100 km/h with a wheel radius of 35 cm
V=ω*r

so rearranged I have

ω=v/r

which is

ω=27.78(m/s)/.35(m)
ω=79.37 (s) ??

Have I got this right or am I way off?
Thanks in advance.

$\displaystyle \omega =$ 79.4 radians/sec

You are correct. You just got the units wrong, which Skeeter corrected for you.
