In hours, it is exactly what you wrote, e.g. 2 hours and 37 minutes, or just over 2 and 1/2 hours (plus 7 minutes). If you want total minutes, every hour has 60 minutes. You would add 60 plus 60 plus 37 to get the total minutes.
4 hours 48 minutes
five and a half hours in total.
129 minutes = 2hours plus 9 minutes left over, or 2.15 hours.
This equals 45 hours and 2 minutes.
it would be 10 hours 15 minutes! 3 hours plus 6 hours is 9 hours 25 minutes plus 50 minutes is 75 minutes, there are 60 minutes in an hour so you have to take 75 minus 60 which leaves you with 15, add the hour onto the 9 hours, gives you 10 hours 15 minutes.
((1 hour 32 minutes) + (2 hours)) + (3 hours 56 minutes) = 7 hours 28 minutes
150 minutes or 2 hours 30 minutes.
to get hours to minutes you multiply your hours by 3600 and to convert minutes to seconds you multiply your number by 60. . . Multiply your hours number by 60 to convert into minutes Add the original minutes number to the product and then multiply the total minutes by 60 to get the total in seconds. Thus 10 hours and 20 minutes . = 10 x 60 = 600 minutes plus the original 20 minutes then = 620 minutes, . which equals 620 x 60 = 37,200 seconds ( phew !!! )
(7.50 hours) + (10 minutes) = 7 hours 40 minutes.
5 hours and 55 minutes.
(10 hours) + (225 minutes) = 13 hours 45 minutes
