Dane:
s₁ = 4 m
t₁ = 2 s
s₃ = 6 m - 4 m = 2 m
t₂ = 5 s - 3 s = 2 s
s₄ = 10 m - 6 m = 4 m
t₄ = 6 s - 5 s = 1s
s₅ = 14 m - 10 m = 4m
t₅ = 10 s - 6 s = 4 s

v₁, v₂, v₃, v₄, v₅ = ?
v₁ = s₁/t₁ = 4 m/2 s = 2 m/s
v₂ = 0 m/s
v₃ = s₃/t₃ = 2 m/2 s = 1 m/s
v₄ = s₄/t₄ = 4 m/1 s = 4 m/s
v₅ = s₅/t₅ = 4 m/4 s = 1 m/s
Całkowity czas ruchu:
tc = 10 s
Całkowita droga:
sc = 14 m
Prędkość średnia:
vśr = sc/tc = 14 m/10 s
vśr = 1,4 m/s
