omega = (pi)/1800 " rads " s^(-1)"

Explanation:

In SI units angular speed is " rad "s^(-1)

The minute hand completes one revolution every hour ( or 3600 secs) and is independent of the size of the clock.

omega = 2pi " rads per hour"

omega = (2pi)/3600 " rads " s^(-1)"

cancel

omega = (pi)/1800 " rads " s^(-1)"
