Answer: At 01:05 p.m. it will overlap again.
Explanation:
Since there are 22 times in a day the minute and the hour hands overlap.
During the first half of the day , it overlaps 11 times and during the rest of the day it overlap 11 more times.
At noon, the minute and the hour hands overlap and after that it will happen at 01:05 p.m.
Since the minute hand completes a full circle in one hour, so it forms 6 degrees per minute .
So, at 01:05 p.m. it will overlap again.

We must sum these 10 numbers
40, 37, 34, 31, 28, 25, 22, 19, 16, 13
The sum would equal the average of the middle 2 numbers times 10.
(28 + 25) / 2 = 53 / 2 = 26.5
We multiply by 10 because there are 10 numbers and this equals
265
