A = 2 * ( 1 h 48 min) + 3* ( 2h + 40 min )

= 2 h + 96 min + 6 h + 120 min

= 8 h + 216 min

216 min  =  3 h 36 min

donc  11 h 36 min

5 * ( 2 h + 3 * 35 min )

=  10 h + 5 *105 min

= 10 h + 525 min

525 min  = 8 h 45 min

donc  18 h 45 min

37 *125 min = 4 625 min

4 625 min =  77 h 5 min

=  3 jours 5 h 5 min

444 x 15 min = 6 660 min

6 660 min =  111 h

Bonsoir!!

A=2x(1h+48min)+3x(2h+40min)

= 2h 96mn + 6h 120mn

= 8h 216mn

= 8h+ 60mn +60mn +60mn +36mn

=> 11h 36mn

B=5x(2h+3x35min)

= 5* ( 2h +105mn)

= 5* (2h +1h +45mn)

= 5  *(3h +45mn)

=  15h +225mn

= 15h +60mn+60mn +60mn +45mn

= 18h 45mn

• C-37x125min

= 37*( 2h 5mn)

= 74h 185mn

= 74h +60mn +60mn +60mn +5mn

= 77h 5mn

• D=444x15min

1h = (15 * 4 )mn

444/ 4

=>111h
