Bonjour
1854min=.......h.......min
1 854/60 =>30h
30 * 60 = 1 800
1 854 - 1 800 = 54
=> 30h et 54mn
800s=.........min.......s
800/60 =>13mn
13 *60 = 780
800-780 = 20
=> 13mn et 20s
7 000s=..........min...........s=.......h.....min......s
7 000/60 => 116mn
116 * 60 = 6 960
7 000-6 960 = 40=> 40s
116/60 = >1h
116 -60 => 56mn
=> 1h 56mn 40s
52000s=........min........s=....h........min.......S
52 000 /60 => 866mn
866*60 =51 960
52 000 - 51 960 => 40s
866/60 = >14h
14 * 60 = 840
866 - 840 => 26mn
=> 14h 26 mn 40s
