Two sets of students are collecting traffic data at two sections, xx and yy, of a highway 1,200 ft apart. Observations at xx show that five vehicles passed that section at intervals of 3, 4, 3, and 5 sec, respectively. If the speeds of the vehicles were 55, 50, 45, 40, and 35 mi/h, respectively, determine the space mean speed (in km/h) for the data using the following equation where u, and u are in km/h. (Round your answer to at least three significant figures.) U = 0.966+ (3.541 km/h) km/h Determine the space mean speed (in km/h) for the data using the following equation. (Round your answer to at least three significant figures.) n i=1 km/h Compare your answers and discuss the results.
