In any circular motion, if the ratio between 2 fellow is n:1 then for each lap of the slower fellow, faster fellow overlaps him n times, except for the last lap of the slower fellow, where the number of crossings are n-1. (The race just finishes before the n th cross. slower fellow : hour hand (short) faster fellow : minuite hand (long) n = 12 Total laps for hour hand = 2 total overlaps = 12+11 = 23.
