The Clock Puzzle
A clock loses 5 minutes every hour. If the clock is set to the correct time at noon, what time will it show when the correct time is 5:00 PM on the same day?
Take your time to think about it, and let me know your answer when you're ready by comment !
Solution:
Since the clock loses 5 minutes every hour, it loses minutes (or 1 hour) over the course of 12 hours.
So, from noon to 5:00 PM, which is 5 hours, the clock will lose minutes.
If the clock shows the correct time at noon and loses 25 minutes by 5:00 PM, it will show the time 25 minutes behind the correct time.
Therefore, the time shown on the clock at 5:00 PM will be 4:35 PM.
