Each of the following automobile trips takes one hour. The positive ? – direction is to the east. (i) Automobile A travels 50 km due east. (ii) Automobile B travels 50 km due west. (iii) Automobile C travels 60 km due east, then turns around and travels 10 km due west. (iv) Automobile D travels 70 km due east. (v) Automobile E travels 20 km due west, then turns around and travels 20 km due east. a. Rank the five trips in order of average ? – velocity from most positive to most negative. b. Which trips, if any, have the same average ? – velocity? c. For which trip, if any, is the average ? – velocity equal to zero?
