A comet on a highly elongated orbit sweeps out

4.0\times10^{14}\,\text{km}^2

of area around the Sun in

10\,\text{days}

. Treat the areal velocity as constant for the entire orbit and answer the following. (i) Calculate the areal velocity of the comet in

\text{km}^2\,\text{day}^{-1}

. (ii) Determine the additional time (in days) the comet will take to sweep out a further area of

1.2\times10^{15}\,\text{km}^2
