12 hours 30 minutes
23 hours 15 minutes minus 45 minutes is 22 hours 30 minutes.
6 hours 15 minutes.
10 hours 18 minutes
(20 hours 30 minutes) - (5 hours 45 minutes) = 14 hours 45 minutes.
1 hour 45 minutes.
3 hours 40 minutes.
19 minutes 30 seconds minus 12 minutes 40 seconds = 6.833 minutes OR 6 minutes 50 seconds.
The result is 12 days 18 hours 50 minutes 58.56 seconds.
1 hour 45 minutes.
From 12:15 am to 2:45 am is 2 hours and 30 minutes. From 12:15 am to 2:45 pm is 14 hours and 30 minutes. From 12:15 pm to 2:45 am is 14 hours and 30 minutes. From 12:15 pm to 2:45 pm is 2 hours and 30 minutes.
To simply work this problem, subtract the hour from hour, and minutes from minutes. I assume you mean both times are morning or evening (not spread from morning to evening). So 9 (hour) minus 8 (hour) is 1 hour. 34 minutes minus 4 minutes is 30 minutes. So, 1 hour and 30 minutes has gone by between 8:04am and 9:34am.If you want am to pm, you'd calculate by 12 hours first, add the remaining hours, then subtract minutes from minutes. 8:04am to 9:34pm would be 8am to 8pm equals 12 plus 9 minus 8 is 1... 12+1 is a total of 13 hours between 8A to 9P. Then, 34 minutes minus 4 minutes is 30 minutes. So between 8:04 AM and 9:34 PM is 13 hours 30 minutes.
