28 mn 54 s + 29mn 12 s +27mn 58s +28mn 1 s exprimer en heures minutes et secondes Svp Merci​

Sagot :

28 mn 54 s + 29mn 12 s +27mn 58s +28mn 1 s

= 112 min 125s

125sec = 60s + 60s+5s=2min 5s

soit 112 min 125s = 114min 5 s

et 114min=60min+54min=1h 54min

donc 28 mn 54 s + 29mn 12 s +27mn 58s +28mn 1 s = 1h54min5s
