Answer
$\frac{\pi}{30}$ radian per min
Work Step by Step
Step 1: The formula to be used here is $w=\frac{\theta}{t}$
Step 2: Since the minute hand of the clock makes one complete rotation in $60$ minutes, $\theta=2\pi$ radians in $t=60$ minutes.
Step 3: Substituting these values in the formula,
$w=\frac{2\pi}{60}=\frac{\pi}{30}$ radian per min
