1. Réponse nonotata
a)5h17min= min
1 h = 60 mn donc 5h = 60x5 = 300 mn
5h17 mn = 300 +17 = 317 mn
b)2h10min34s= s
1h = 3600seconde donc 2 h = 3600x2 = 7200s
1mn = 60 s donc 10 mn = 600s
2h10mn34s = 7200+600+34 = 7834 s
c)347min= h min
1h = 60 mn 347 mn = 347 /60 = 5,7833 heures
0..7833x60 =47 mn
donc
347 mn = 5h 47mn
d)5425s= h min s
1h = 3600s
5425/3600 = 1,5069444heures
0.506944x60 = 30.4166667 mn
0.416667x60 = 2s donc
5425s = 1h30mn2s
e)23,59 h= h min s
0.59h = 0.59x60 = 35.4 mn
0.4 mn = 0.4x60 = 24s
23.59h = 23h 25mn 24s
