The following equation shows Kepler's 3^{rd} law of planetary motion. It relates the time, t (in days), that a planet takes to revolve once around our sun to the distance, d (in kilometers), of that planet from the sun.

t^{2} = 3.98•10^{-20}•d^{3}

Mars is approximately 4 times as distant from the sun as Mercury is.

About how many times longer would Mars's revolution time be than for Mercury? Round your answer to the nearest whole number.
