1 day = 24 hrs, and 1 hr=60 min. Therefore 1 day=1440 min. Therefore 1 day + 4 hrs + 7 min equals 1440 min + 240 min+ 7 min or 1687 minutes. Applying the same principal to the other side of the equation gets us 360 min + 20 min or 380 min. 1687 minutes - 380 minutes = 1307 minutes. This equals 21 hrs 47 min.
10 hours and 15 minutes
75 Since one hour has 60 min, all you have to do is add 15 min and that equals 75 min.
