Besoin d'aide 27km/h=....m/s 10m/s=......km/h 0,95km/min=....km/h 1,5km/min=.....m/s Merci d'avance

27km/h=....m/s: 27 000 m /3600s= 2700/36 = 75
10m/s=......km/h =,0,01/ (1/3600)= 36
0,95km/min=....km/h: 0,95 X 60 = 57
1,5km/min=.....m/s: 1500/60 = 25

27 000 m /3600 s = 2700/36 = 75
0,01/ (1/3600)= 36
0,95 X 60 = 57
1500/60 = 25
