When is the next time Jack' clock will be exactly on time?

  1. Oct 12, 2003 #1
    Jack has an antique cuckoo clock. It's a lovely clock, but it runs too slowly; it loses 9 minutes of time every hour. Sam visits his friend Jack one day, and notices that the cuckoo clock is exactly on time at noon on Tuesday.
    When is the next time Jack' clock will be exactly on time?
