A trailer from a minor road joins a major road traffic stream having a flow of 2000 veh/hrand a density of 18veh/km. The heavy traffic in the opposite stream makes it difficult forvehicle to overtake it once in the traffic stream. The trailer moves at a speed of 60Km/hr forstretch of 15km. The effect of the entry of the trailer into the traffic stream is an increase inthe density of the traffic behind to 30 veh/Km. Determine the number of vehicles that willbe in the traffic stream when the trailer eventually leaves
