Question

11 Carmin Carmin The figure on the right shows the intersections of three one-way streets. To keep traffic moving the number of cars per minute entering an intersection must equal the number exiting that intersection. The following is the system of equatons for the intersections by 12, and by X+ 11 y 13 2+13 -x+ 5 y6-2011 13 Carmin 13 Carmin Carmin 11 Carmin The solution to the system is fit - 8,16,1)). If construction limits z to 3 cars per minute, how many cars per minute must pass between the other intersections to keep traffic flowing? To keep traffic flowing, cars per minute and y cans per minute must pass through the other intersections, (Simplify your answers

Answer 1

2+11-7 +13 Griven system of equation 7+13=ars y + 5 2771 The solution of the system is (448, t+6, t) a=t+s, y=x+6, 2-t I f z=3 then =3+8 u ?ye3+6=9 To keep trafic az a = [11] cans pen minute and cars pen must pass through the other intensections & '. y=9 minute

Hope it helps.
