How many times during a single 12-hour cycle do the minute hand and hour hand of an analog clock overlap precisely?
11 times
Although there are 12 hours, the hour hand moves while the minute hand circles. The overlaps happen every 12/11 hours (approximately every 1 hour, 5 minutes, and 27 seconds), resulting in exactly 11 overlaps per 12 hours.
