The accompanying figure shows a network of one-way streets with traffic flowing in the directions indicated. The flow rates along the streets are measured as the average number of vehi- cles per hour. (a) Set up a linear system whose solution provides the un- known flow rates. (b) Solve the system for the unknown flow rates. (c) If the flow along the road from A to B must be reduced for construction, what is the minimum flow that is required to keep traffic flowing on all roads? 400 | | 750 300 X3 250 A X4 400 B 200 100T |300 Figure Ex-3
