How many times does the minute hand meet the hour hand in a
day?
Answer Posted / kerobotz
After starting at 12am they don't meet back up at 1:05am
they actually meet back up at 1:05 and 27.27 secs. This
extra time adds up over the course of the morning and after
11 hours becomes 5 mins.
Therefore it is 22 times in a day.
The math:
min_hand completely rotates 1/hr
hr_hand completely rotates (1/12)/hr
They unite at time t when t(1-1/12)=1
==> t=1/(1-1/12)
=1/(11/12)
=12/11
==> t is 1.0909 hours
