bonjour
1 h 654 min 321 s
654 min = 10 * 60 + 54 donc 10 h 54 min
321 s = 5 * 60 + 21 donc 5 min 21 s
1 h 654 min 321 s = 11 h 59 min 21 s
567 890 s = 157 * 3600 + 2 690 = 157 h 2690 min
157 h = 6 * 24 + 13 = 6 jours 13 h
2690 min = 44 *60 + 50 = 44 min 50 s
567 890 s = 6 j 13 h 44 min 50 s
3.08 h = 3 h + 0.6 *0.8 = 3 h 4 min 48 s
5.716 h = 5 h 42 min 57 s
2 h 6 min 54 s = 2 h + 6 /60 + 54 /3600 = 2.115 h
36 min = 36/60 = 0.6 h
Bonjour,
1) 654 mn = (10 × 60) mn + 54 mn = 10 h 54 mn
321 s = (5 × 60) s + 21 s = 5 mn 21 s
donc : 1 h 654 mn 321 s = 1 h + 10 h + 54 mn + 5 mn + 21 s
= 11 h 59 mn 21 s
567 890 s = (157 × 3 600) s + 2 690 s = 157 h 2 690 s
157 h = (6 × 24) h + 13 h = 6 j 13 h
2 690 s = (44 × 60) s + 50 s = 44 mn 50 s
donc : 567 890 s = 6 j 13 h 44 mn 50 s
3,08 h = 3 h + (0,08 × 60) mn = 3 h 4,8 mn = 3 h 4 mn (0,8 × 60)s = 3 h 4 mn 48 s
5,716 h = 5 h + (0,716 × 60) mn = 5 h + 42,96 mn
= 5 h + 42 mn + (0,96 × 60) s
= 5 h 42 mn 57,6 s
2 h 6 mn 54 s = 2 h + (6/60) h + (54/3600) h = 2,115 h
36 mn = (36/60) h = 0,6 h
