This is a three-part problem. Two sets of students are collecting traffic data at two roadway stations, station 130 + 00 and station 145 +00. Observations at station 130 + 00 show that five vehicles passed that section at intervals of 0, 3, 4, 3, and 5 sec, respectively. If the speeds of the vehicles were 50, 45, 40, 45, and 50 mph respectively. Note: Stationing is fundamental to highway plans. A station is the horizontal measurement along the Construction Survey Line of a project. Distances are measured and points are identified on plans with reference to station numbers. One hundred feet is equivalent to one station. Highway stationing might be compared with a rope having knots at 100-foot intervals. The beginning end of the rope would be 0, the first knot at 100 feet would be Station Number 1 and would be written as 1+00. The second station number would be 2 (which is 200 feet from the beginning) and would be written as 2+00, and so on. Part A. Determine the time mean speed, in mph.…
