I think the answer is 64.5
In order to find what 10% of a day is:
A day is 24 hours long.
Divide 24 by 100, then multiply the answer by 10.
24/100=0.24
0.24*10=2.4
So, 10% of the day is 2.4 hours.
2 hours and 30 minutes can be written as a decimal as 2.5.
So, 2 hours and 30 minutes is slightly more than 10% of the day.
