Rappel des 3 formules :
v=d÷t
d=v×t
t=d÷t
1) Là on veut savoir le temps qu'elle a mis, donc on va faire :
t = d÷v = 8 ÷ 40 = 0,2h
0,2 × 60 = 12
Elle mettra 12 minutes.
2) Même chose
t=d÷v = 8÷48 ~0,17h
0,17×60~10min
Elle mettra 10min.
3) 10min - 8min = 2min
Aymerie a gagné 2minutes de plus que Lisa.
