Grandfather Clock Riddle

Grandfather Clock Riddle
A grandfather has a broken grandfather clock that is off by a minute every hour (too fast). He figures out a way, while keeping it running at the same rate, to make the clock say the correct time twice a day.

How could he do this?

    If only he can make it run backwards!

  • brent

    He can replace the face of the clock with a backwards dial.

    This is similar spirit to Anant’s suggestion, and also takes the riddle’s picture into account.

  • Margot

    Every half hour, he opens the pendulum case and stops the pendulum for 1/2 minute (watching the second hand on his watch). He then starts the pendulum again.
    I wouldn’t think it would be a satisfying way to spend the day, but if that’s what he wants…so be it.

    He can stop winding it..or unplug it. When it is stopped…the clock will be right twice a day.

  • Anant, you are today’s winner!
    He made it run backwards.

  • Baudizzle

    Didn’t think of that!

    But wouldn’t sending it in the other direction actually result in it telling the correct time 4 or 5 times a day?
