1 hour = 60 min

1 day = 24 hours = 24 * 60 = 1440 min

1 hour 18 min = 78 min


D = Day

N = Night


D = N + 78


D + N = 1440 min

N + 78 + N = 1440

2 N + 78 = 1440

2 N = 1440 - 78 = 1362

N = 1362 / 2 = 681 min

D = N + 78 = 681 + 78 = 759 min



12 * 60 = 720

759 - 720 = 39

759 min = 12 h 39 min


D = 12 h 39 min
