Bamey wishes to drive his racing car the length of a straight track at high constant speed u. His service man Clyde has observed from the pit stop that the car consumes fuel at the rate n/t (in droplets of fuel injected in the carburetor per second). Clyde has filled the tank with exactly enough fuel for Barney to drive the course. What rate does Barney measure for his fuel consumption? Does he observe his car to reach exactly the end of the track, to run short, or to have fuel left over at the end? You must show work!!!
