Next Class: Complicated Problems

  • When would three hands of a clock all overlap?

  • It is now past 3 o'clock in the afternoon. The minute hand is 3 minutes from now will be directly opposite the hour hand 9 minutes ago. What is the time now?

  • A clock is operating normally. It is now sometime between 7:00 and 8:00. In less than one hour, the minute hand and the hour hand will have exactly exchanged positions. Find the number of minutes after 7:00 that the time is now.

  • An absent-minded watch repairman connected the hour hand to the minute hand pinion and the minute hand to the hour hand pinion and set the clock at 6AM which was the correct time then. How soon after 6AM will this clock give the correct time again? How many times during the day would clock show correct time?

  • In a clock with identical dials for hours and minutes, how many times a day you can’t tell the time?
