A clock gains 5 minutes every hour. It was set to the correct time at 12:00 PM (noon). What real time is it when the clock shows 3:15 PM on the same afternoon?
3:00 PM
For every 60 minutes of real time, the clock advances 65 minutes. A clock time of 3:15 PM represents 195 minutes past noon on the faulty clock. Dividing 195 by 65 gives 3 hours of real time, meaning the actual time is 3:00 PM.
