2. Two sets of students are collecting traffic data at two sections, xx and yy, of a highway 1550 feetapart. Observations at xx show that five vehicles passed that section at intervals of 3, 4, 3, and 5seconds.A. If the speeds of the vehicles were 50, 45, 40, 35, and 30 mi/hr, draw a schematicshowing the locations of the vehicles 20 sec after the first vehicle passed section xx.Assume that each vehicle maintains a uniform speed. (5 + 1 = 6 points)B. Determine the time mean speed. (2 points)C. Determine the space mean speed. (2 points)D. Determine the density of the highway. (2 points)
