Four race cars are traveling on a 2.5-mile oval track. The four cars are traveling at constant speeds of 195 mi/h, 190 mi/h, 185 mi/h, and 180 mi/h, respectively. Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it passes by your location. a. What is the time-mean speed for these vehicles during this time period?b. Assume that you were given only an aerial photo of the circling race cars and the constant travel speed of each of the vehicles. What is the time-mean and space-mean speed for these vehicles?
