Verified Answer
A certain harbor has docking stations along its west and south docks, ...
The boat traveled in a straight line from docking station #2 on the west dock to one of the docking stations on the south dock, passing through a single point that is both due east of docking station #4 and due north of docking station #7. Call this point P. Having traveled to P, the boat was both 2d south of its starting point and 2d east of its starting point. Therefore, traveling in a straight line, the boat traveled one unit south for every one unit traveled east. And because at point P the boat was a distance d north of the south dock, the boat must have reached the south dock at a point which is a distance of d east of docking station #7 (which is due south of point P). This point is the position of doctang station #8. The boat therefore arrived at docking station #8.
