Oh, dude, let me grab my calculator for this intense math problem... Okay, so from 9:00 am to 5:00 pm is 8 hours, right? And then we have an extra 45 minutes, which is like 0.75 hours. Add those up, and you get a grand total of 8.75 hours. Math wizard strikes again!
It is 9 hours.
10 hours and 15 minutes.
6 hours and 30 minutes.
8:45 AM - 5:45 PM 9 hours have passed.
