0.4 hours is 24 minutes.
It is: .04 of 60 = 2.4 minutes
A quarter to an hour is 15 minutes to the hour. As there are 60 minutes in an hour, this is also 45 minutes after the previous hour. So a quarter to 5 is 45 minutes after 4. However, 4am is 04:00 and 4pm is 16:00, so a quarter to 5 is either 04:45 or 16:45 depending upon whether it is am or pm.
1 hour 34 minutes 0:30 + 1:00 + 0:04

A quarter to an hour is 15 minutes to the hour. As there are 60 minutes in an hour, this is also 45 minutes after the previous hour. So a quarter to 5 is 45 minutes after 4. However, 4am is 04:00 and 4pm is 16:00, so a quarter to 5 is either 04:45 or 16:45 depending upon whether it is am or pm.
There are 60 seconds per minute and 60 minutes per hour. Therefore there is 3600 seconds per hour.141 seconds ÷ 3600 seconds per hour = .04 HoursSo 141 seconds is approximately .04 Hours.
1 hour 34 minutes 0:30 + 1:00 + 0:04
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.
