An hour hand goes around once every 12 hours. So, it's speed in RPM is 1/(12*60) = 1/720

Correct answer:
On a 12 hour clock the hour hand makes 1/720 of a revolution per minute.
On a 24 hour clock the hour hand makes 1/1440 of a revolution per minute.

Well, obviously 60*12 takes a round. So 1/(60*12) is its speed in RTM.
The answer is thus 1/720.
Right?..

You have 3 correct answers so far.
The correct answer is: 1/60 rpm.
The hour hand makes one full revolution in 60 minutes.....so it's 1 revolution/60 minutes........1/60 (rpm).

It rotates once per hour, so it rotates 1/60's of a full rotation per minute. 1/60 is .01667 RPM's.

There are a lot of very odd clocks out there with hour hands going round once in an hour. Mine doesn't.
