8 km
———————
Assuming they start at the origin and A heads East along the +x axis, then A ends up at (-1,-4) while B ends up at (-1,4). [ If you assume A heads West first then A ends at (1,4) and B ends at (1,-4) ... so even though their ending places are different, the distance between them is the same, 8km. ]
