Odpowiedź:
a) s = v*t
s₁ = 32 km
v₁ = 8 km/h
t₁ = s₁/v₁
t₁ = 32 km / 8 km/h
t₁ = 4 h
s₂ = 18 km
t₂ = 2 h
b)
s = v*t
t₃ = 2 h
v = 12 km/h
s₃ = 12 km/h * 2 h
s₃ = 24 km
s₄ = 18 km
v = 9 km/h
t₄ = s₄/v
t₄ = 18 km/9 km/h
t₄ = 2 h
c)
s₅ = 24 km
t₅ = 3 h
t₆ = 4 h
v = 11 km/h
s₆ = v* t
s₆ = 11 km/h * 4 h
s₆ = 44 km
łączna droga
s = 32 km + 18 km + 24 km + 18 km + 24 km + 44 km
s = 160 km
całkowity czas
t = 4 h + 2 h + 2 h + 2 h + 3 h + 4 h
t = 17 h
Odp. Łączna ddroga to 160 km, a czas to 17 h
