Traffic Flow The traffic through downtown Johannesburg follows the one-way system shown below, with traffic movement recorded at incoming and outgoing streets (in cars per minute) as shown.
a. Set up and solve a system of equations to solve for the traffic flow along the middle sections of the four streets.
b. Is there sufficient information to calculate the traffic along the middle section of Jeppe Street? If so, what is it? If not, why not?
c. Given that 400 cars per minute flow down the middle section of Bree Street, bow many cars per minute flow down the middle section of Simmons?
d. What is the minimum traffic flow along the middle section of Harrison Street?
e. Is there an upper limit to the possible traffic down Simmons Street consistent with the information given? Explain.
