How do I add hours and minutes?
Add minutes to minutes and hours to hours, then carry every 60 minutes into an hour. 2 h 45 min + 1 h 30 min = 3 h 75 min = 4 h 15 min.
How do I turn minutes into decimal hours?
Divide by 60. 4 h 15 min is 4.25 hours; 7 h 40 min is about 7.67 hours. The “in hours” line does this for you.
