A) It is designed to minimize the maximum possible travel distance to any of the locations.
B) The optimal x- and y-coordinates are calculated separately.
C) The optimal solution is unconstrained, so it could suggest a location in the middle of a body of water.
D) The weights used are the quantity of goods moved to or from each location.
E) The origin of the coordinate system and the scale used are arbitrary, just as long as the relative distances are correctly represented.
