Explanation

The hands of a clock coincide 11 times in every 12-hour period. They do not coincide between 11 and 1 o'clock (only at 12:00).

AI explanation

Applying the coincidence rule for clock hands, the minute hand laps the hour hand 11 times every 12-hour period, which occurs at intervals of 65 5/11 minutes. Between 1 hour and exactly 12 hours, the overlapping occurrences happen starting at 1:00:00 and continue exactly 11 times until the cycle culminates at 12:00:00. The hands will coincide 11 times.
