  • S₁ = 6 km, ke U
    S₂ = 8 km, ke T
    t = 2 jam

    jarak
    d = S₁ + S₂
    d = 6 + 8
    d = 14 km ✓

    perpindahan
    S = √(S₁² + S₂²)
    S = √(6² + 8²)
    S = 10 km ✓

    kelajuan
    |v| = d / t
    |v| = (14 km) / (2 jam)
    |v| = 7 km/jam ✓

    kecepatan
    v = S / t
    v = (10 km) / (2 jam)
    v = 5 km/jam ✓
