    Saturn orbital period

    p (s) = 29.46years

    Average distance

    a (s) = 9.54AU

    Venus orbital period

    p (v) = 0.62 years

    a (v) ?

    Using Kepler's third law

    a³ ∝p²

    a³ = kp²

    a³/p² = k

    Where

    a is the distance if planet from sun

    T is the period of the planet

    Then,

    a (Venus) ³/p (venus) ² = a (saturn) ³/p (saturn) ²

    a (v) ³/p (v) ² = a (s) ³/p (s) ²

    a (v) ³ / 0.62² = 9.54³/29.46²

    a (v) ³ / 0.62² = 1.0004

    a (v) ³ = 1.0004 * 0.62²

    a (v) ³ = 0.3846

    a (v) = cube root (0.3846)

    a (v) = 0.727 AU

    15.66 AU

    Explanation:

    Using Kepler's law which states that T² ∝ R³ where T = period of planet and R = distance of planet from sun.

    So T₁²/T₂² = R₁³/R₂³

    where T₁ = orbital period of Saturn = 29.46 years

    T₂ = orbital period of Venus = 0.62 years

    R₁ = average distance of Saturn to the sun = 9.54 AU

    R₂ = average distance of Venus to the sun = ?

    From the equation above,

    R₂³ = (T₂²/T₁²) R₁³

    R₂ = [∛ (T₂/T₁) ²]R₁

    R₂ = [∛ (0.62/29.46) ²]9.54 AU

    R₂ = [∛ (0.021) ²]9.54 AU

    R₂ = [∛0.000443]9.54 AU

    R₂ = [0.0762]9.54 AU

    R₂ = 0.727 AU
