The minute and the hour hand of a watch meet every 65 minutes.
How much time does the watch lose or gain ?
(In reply to Another Question!
The hands move at 144/143 times as fast as a perfectly accurate watch, so after 143 12-hour periods the watch will have traveled through 144 12-hour cycles. After 72.5 days this will take place, or the midnight at the end of September 10, beginning of September 11.
