At the Indianapolis 500 time trials, each car makes four consecutive laps, with its overall or average speed determining that car’s place on race day. Each lap covers 2.5 (exact). During a practice run, cautiously and gradually taking his car faster and faster, a driver records the following average speeds for each successive lap: 200 , 210 , 220 , 230 .
His average speed will be
