his question has more than one correct answer and all must be selected. Select all the statements that are true regarding the centre-of-gravity method. The weights used are the quantity of goods moved to or from each location. It is designed to minimize the maximum possible travel distance to any location. The origin of the coordinate system and the scale used are not arbitrary, so the relative distances are incorrectly represented. The optimal solution is unconstrained, so it could suggest any location in the middle of a body of water. The optimal x - and y-coordinates are calculated separately
