Two guns \( A \) and \( B \) can fire bullets at speeds \( 1 \mathrm{~km} / \mathrm{s} \) and \( 2 \mathrm{~km} / \mathrm{s} \), respectively. From a point on a horizontal ground, they are fired in all possible directions. The ratio of maximum areas covered by the bullets on the ground fired by the two guns is
