The figure shows the intersections of three oneway streets. lbe numbers g;,,n represent IJaffic How. in cars per bour. at a peak period (from 4 P.M.to6 P.M.). a. Use the idea that the 350 ;r 300 number or cars entering 700 20l each intersection per hour must equal the number of cars lea"ing per hour to .set up a system of linear equations invohing .t. J. and :. b. Use Gaussian elimination to solve the system. c. If construction Limits the value of: to 400, how many c-ars per hour must pass between the other intersection." to keep traffic flowing?
