Two aircraft A and B are at the same height and are travelling horizontally at 500km/h. A is flying due north and B is flying due west. The bearing of B from A is 15 and the distance AB is 10km.

(i) Find the least distance between the aircraft in their subsequent motion.

(ii)the time, in seconds , for them to reach the position where they are the least distance apart.
