A section of highway is known to have a free-flow speed of 50mph and a capacity of 3600 veh/h. In a given hour, 2400 vehicles were counted at a specified point along this highway section. If the linear speed-density relationship (greensheild model) applies, what would you estimate the space-mean speed of these 2400 vehicles to be?
