clock mystery


There are two clocks such that one clock gains 1 minute every hour and the other clock loses 1 minute every hour. If they show the correct time now, then after how many hours will they show a difference of 1 hour?








AnswerAfter 30 hours, the first clock will show 30 minutes more than the actual time, while the second clock will show 30 minutes less than the actual time, which totals to a difference of 1 hour.
