R3271 minutes. Assuming that the constant is the same for all sections of road, the total time for all 439 vehicles to be in this network is 397231 + 216372 I kmg l 239.1124 l R3325 minutes What is the total time if k = 3? a. None of these choices b. (3t + sr t, 2t + s, t, s) where t and 5 go from 439 to 8?8 minutes c. 439 minutes d. (3t + s, t, 2t + s, tr 5) where t and 5 go from 0 to 439 minutesx e. 3951 minutes f.3 minutes Consider the following traffic flow diagram: If the flow in, at intersection A, is 439 cars and the flow out, at D, is 439 carsr consider the following question: the total time it takes vehicles to travel along any stretch of road is proportional to the traffic along that stretch. For example, the total time it takes the vehicles along AB is fan minutes.
