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 vehicles per hour.
(a) Set up a linear system whose solution provides the unknown flow rates.
(b) Solve the system for the unknown flow rates.
(c) If the flow along the road fromAto B must be reduced for construction, what is
the minimum flow that is required to keep traffic flowing on all roads?
