R&T Whoselares distributes general merchandise to retailers across India. There are numerous warehouses located throughout the country that serve as points of sale and warehouses for delivery vehicles that serve retailers in the cities surrounding the warehouses. The warehouse serving the districts of Prakasam, Guntur, Krishna, West Godavari and East Godavari is located in Vijayawada. Delivery volume is represented in terms of average sales activity per city visit, which groups stops at a number of retailers within each city. From a map of the warehouse region (the table), linear coordinates are constructed for the warehouse and for each city. The coordinates have a scale factor on the map of 1 coordinate unit = 12.3 kilometers. The circuit factor that converts computer-coordinated distances to road distances is 1.12. The capacity of the vehicles is 500000 in terms of sales. Determine the minimum routes that guarantee compliance with the volumes at each of the points.
