The clocks will show 14:45 (2:45 pm).


You can solve this problem by using the fact that one day contains 24 hours.

That means that if you add 24 hours to your time, it will still show 10:45. The same goes for adding 48 hours, it will still show 10:45, only it will be two days from now.

So, use the number of hours to determine how many complete days , i.e. 24 hours, you'd get

#100color(red)(cancel(color(black)("hours"))) * "1 day"/(24color(red)(cancel(color(black)("hours")))) = 25/6 = 4 1/6"days"#

This means that you add 4 full days, whiuch make up for 96 out of the 100 hours, and #1/6"th"# of a day, which is equivalent to 4 hours.

Adding four full days will not change the time, so it will still be 10:45 only four days from now. Adding four hours will make the time

#14:45" "# or #" "2:45 "pm"#
