Problem of the Month

What Time Is It?



Tossing and turning in my bed on New Year's Eve, I woke up to find the hour hand of my wall clock pointing directly at the 22-minute mark.

What time did I wake up?



Solution to the Problem:

4:24 AM

If the hour hand is pointing directly at the 22-minute mark, it is 2/5 of the way between 4 and 5.   Since 2/5 of an hour is 24 minutes, and it is nighttime, the time is 4:24 AM.
