Imagine a 24 hour clock with minute and hour hands. How do the rotational speeds of these hands compare to a regular clock’s hands?
minute hand is same speed ... once around per hour
hour hand on 24-hr clock is half the speed of a 12-hr clock
... once around in 24 hr vs. twice around
alright
To understand the rotational speeds of the hour and minute hands on a 24-hour clock compared to a regular clock, let's start by understanding how the two systems work.
In a regular clock, which uses a 12-hour time format, the hour hand completes a full rotation every 12 hours, while the minute hand completes a full rotation every hour. This means that the hour hand moves at a slower rate than the minute hand.
Now, let's transition to a 24-hour clock. In this system, a full rotation of the hour hand takes 24 hours, while the minute hand still completes a full rotation every hour. Thus, on a 24-hour clock, both the hour and minute hands move at the same speed as they do on a regular clock. The only difference is that the hour hand takes twice as long to complete a full rotation since it needs to cover 24 hours instead of 12 hours.
In summary, the rotational speeds of the hour and minute hands on a 24-hour clock are the same as those on a regular clock, with the only difference being that the hour hand on a 24-hour clock takes 24 hours to complete a full rotation instead of 12 hours.
