URGENT!!!!!!!!!!!!! SVP!!! AIDEZ MOI

Exercice 2

1/
D = 320 - 110
D = 210 km

2/
Partie 1
D= 110 Km
T = 2h12min = 2,2h

V = D / T
V = 110 / 2,2
V = 50 km/h


Partie 2
D= 210 Km
T = 5h - 2,2h = 2,8h

V = D / T
V = 210 / 2,8
V = 75 km/h


3/
Vm = D / T
Vm = 320/5
Vm = 64km/h


4/
Vm1 = (75 + 50)/2
Vm1 = (125)/2
Vm1 = 62,5 km

Vm2 = 64 km

Non Vm1 # Vm2 ( # : différent)
