hi guys,

need help with this question.





cheers

Since there's no equation given for the curve I guess the only thing to do is just to approximate and read off the graph.

8. a) Maximum flow would be the highest point on the graph which occurs to be at ~ (60,35)

Which means the speed is 60 km/h and the maximum flow is 35 vehicle/min

b) Let the vertical axis be y and horizontal axis be x.

When x = 20

when x = 60

So the original flow is 26 vehicle/min and this increases to 35 vehicle/min

would be %

c) Use the same principle as b)
