Two Clocks
  • I started 2 analog clocks (12 hours on each face) at the same time. I know one of them runs 2 minutes too slowly each hour while the other goes one minute too fast each hour. Assuming they show the same time when I start them, how long will it be until both clocks show the same time again? That is, both the minute and hour hands match the initial time.
