Shockwave Problem: Rolling Roadblock

Flow on a road is $q_{1} = 1800 v e h / h r / l a n e$ , and the density of $k_{1} = 14.4 v e h / k m / l a n e$ . To reduce speeding on a section of highway, a police cruiser decides to implement a rolling roadblock, and to travel in the left lane at the speed limit ( $v_{2} = 88 k m / h r$ ) for 10 km. No one dares pass. After the police cruiser joins, the platoon density increases to 20 veh/km/lane and flow drops. How many vehicles (per lane) will be in the platoon when the police car leaves the highway?
