To find out when Mr. Ahmad finishes his work, we need to add 12 hours and 45 minutes to his starting time of 11:40.

First, convert 12 hours and 45 minutes into minutes only.
12 hours = 12 * 60 = 720 minutes
So, 12 hours and 45 minutes = 720 + 45 = 765 minutes

Next, add the 765 minutes to the starting time of 11:40.

11:40 + 765 minutes = 12:05

Therefore, Mr. Ahmad finishes his work at 12:05 on Tuesday, using the 24-hour clock format.
