Studies have shown that the traffic flow on a 2 lane highway adjacent to school can be described by the Greenshield's model. A length of 0.50 km adjacent to a school is described as a school zone and operates for a period of 25 minutes just before the start of school and just after the close of school. The posted speed limit for the school zone during its operation is 21 kph. Data collected at the site when school zone is not in operation show that the jam density and mean free for each lane is 119 veh/km and 65 kph respectively. If the demand flow on the highway at the tìme of the operation of the school zone is 95% of the capacity of the highway, calculate the following:

What is the area of ABED if AB is parallel to CE and BCD is a right-angled triangle at B having area 30 square metres?
C) A 20-mile strip of terrain is to be photographed for highway mapping. The aerial camera to be used has a lens of focal length 12 in and takes 9×9 inches photographs. The ground elevation varies from a low of 800.00 ft to a high of 1050.00 ft above mean sea level. The plane has to make one flight line and the average width of the photographic coverage is to be 1650.00 ft. What will be the average scale of the photographs? What flying height, above mean sea level, should be used for this flight? If it is specified that the overlap (end lap) between photos be 60% and that 2 extra exposures be added at each end of the flight line, find how many photographs will be required.
