Sky Bus has to decide on location of its hub. There are 6 possible destinations for the buses it operates. Suppose that the center of town will be used as the reference for describing the possible destinations. A is located 50 miles South and 30 miles West. B is located 30 miles North and 20 miles East. C is located 10 mile South and 50 miles East. D is located 20 miles North and 30 miles West. E is located exactly in the center of town. F is located 100 miles North and 50 miles East. Assume that traffic to each destination will be equal. Where should the hub go so that travel time is minimized?
