11-20 A road construction project would increase the road capacity around the outside roads from International Drive to Disney World by 175 cars per hour (see Problem 11-19). The two paths affected would be 1-2-6-9-11 and 1-5-8-10-11. What impact would this have on the total flow of cars? Would the total flow of cars increase by 350 cars per hour?

11-19 The road system around the hotel complex on International Drive (node 1) to Disney World (node 11) in Orlando, Florida, is shown in the network of Figure 11.27. The numbers by the nodes represent the traffic flow in hundreds of cars per hour. What is the maximum flow of cars from the hotel complex to Disney World?
