For the hour hand, if it went from 12 pm to 4pm, doesn’t that mean that the hour hand circled 4 times to get from 12pm to 4pm? 12 - 1, 1 -2, 2-3, and then 3pm to 4pm? Then wouldn’t that be 4 times the circumference + the 1/3 circumference (4 pie) that Greg found in this video?
The hour hand and the minute hand of a clock move differently. From 12 PM to 4 PM, it’s a span of 4 hours.
-The hour hand only moves 1/3 of the full clock during those 4 hours because the clock is divided into 12 hours, and 4 hours is just a third of that (4 out of 12 hours).
-In each hour (like from 12 to 1), the hour hand moves one step, covering 60 minutes worth of space on the clock. Over 4 hours, it moves 4 steps or 240 minutes on the clock.
The minute hand, however, completes a full circle every hour, as it has to count all 60 minutes before the next hour starts. Since there are 4 hours, the minute hand will circle the entire clock 4 times.
If we were to assume the hour hand circled the clock 4 times, that would mean it covered 4 full rotations, which equals 96 hours (since 1 full rotation represents 12 hours × 4). That doesn’t happen here, as it only moves for 4 hours, covering a small portion of the clock.
So, the idea of “4 times” applies only to the minute hand because it completes one full rotation every hour, not the hour hand.
