3 hours, 26 minutes, 0 seconds.
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.
Two minutes less than an hour. 10 hours, 23 minutes
((1 hour 32 minutes) + (2 hours)) + (3 hours 56 minutes) = 7 hours 28 minutes
(5.30 hours) + (1 hour 49 minutes) = 7 hours 7 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.

Your 1.2 hours is 1 hour and 12 minutes, or 72 minutes. You know an hour is 60 minutes, so 0.1 hours is 6 minutes. You can work that in your head. If 0.1 hours is 6 minutes, then 0.2 hours is twice that, or 12 minutes. The 1 hour, the 60 minutes, plus 12 minutes is 72 minutes. You don't need a calculator for this one.
