Town is at point (0,0); town b is at point (400,300); town c is at point (800,1500); and point d is at point (1300,1500). There are two highways that connect town a to town d. Route 1 goes through town b and then onto town d. Route 2 goes through town c and then onto town d. If a fleet of 100 automobiles are to be shipped to town d by truck, which of the two routes minimizes cost of route 1 cost $22 per mile and route 2 costs $21 per mile? And by how much? Hint: use the distance formula
