What is the rotational speed of the hour hand on a clock?

It goes 2PI radians in ...

Hmmm is this a 12 hour clock, or a 24 hour clock?

Assume 12 hours
speed=2PIrad/12hours
you can convert that to minutes or seconds if you wish. Or even days..
speed=2PIrad/.5 days

To determine the rotational speed of the hour hand on a clock, we need to know the time it takes for the hour hand to complete one full revolution, which is 360 degrees.

The hour hand on a standard clock completes a full rotation in 12 hours. To calculate the rotational speed, we can convert 12 hours into minutes to get a more standard unit of time.

There are 60 minutes in an hour, so in 12 hours, there are 12 x 60 = 720 minutes.

Therefore, the rotational speed of the hour hand on a clock is 360 degrees in 720 minutes, or 0.5 degrees per minute.
