how often does the minute hand pass the hour hand on an analog clock?
As the hour hand must move a bit more than one hour to catch up to the minute hand. Specifically it moves 12/11 of an hour or 65.454545 minutes. Thus the correct times where minute hand pass the hour hand are:
0:00:00 (midnight)
1:05:27
2:10:55
3:16:22
4:21:49
5:27:16
6:32:44
7:38:11
8:43:38
9:49:05
10:54:33
12:00:00 (noon)
13:05:27
14:10:55
15:16:22
16:21:49
17:27:16
18:32:44
19:38:11
20:43:38
21:49:05
22:54:33
24:00:00 (which doesn’t count because it’s in the next day)
So there are 22 crossings. Note that there is NO overlap in the expected area of 11:55 because it happens at 12:00. You can spin the time setting knob on an analog clock and see this easily.
No. of hours in a day = 24 hours
No .of passing between minute hand and hour hand = 22
Time needed by minute hand to pass the hour hand = 24 hours/22 = 1 hours 1/11 minute.
