bonjour
5 h 18 min = 5 *60 + 18 = 318 min
14 min 31 s = 14 *60 + 31 = 871 s
3 900 s = 1 h 300 min = 1 h 5 min
2 h 12 min = 2 h + 12/60 = 2.2 h
88 min = 1 h 28 min
6 h 35 = 6 h 21 min
1 h 48 min = 3 600 + 48*60 = 6 480 s
515 min = 8 h 25 min
4 h 27 min = 4.45 h
3 h 36 min = 3.6 h
1.8 h = 108 min
0.15 h = 540 s
55 min 11 s = 56.85 min
1 h 60 s = 1 h 1 min
3 h 85 min 103 s = 4 h 26 min 43 s
3 h 96 min = 4 h 36 min
59 min 60 s = 60 min = 1 h
87 min 97 s = 88 min 37 s = 1 h 28 min 37 s
la suite, tu fais des soustractions
