8. 15 points HHCalcCustom1 5.1.015. My Notes Ask Your Teacher Roger runs a marathon. His friend Jeff rides behind him on a bicycle and clocks his speed every 15 minutes. Roger starts out strong, but after an hour and a half he is so exhausted that he has to stop. Jeff's data follow. Time since start (min) 0 1530 4560 7 90 15 14 13 1311100 Speed (mph) 15 (a) Assuming that Roger's speed is never increasing, give upper and lower estimates for the distance Roger ran during the first half hour. ower estimate miles upper estimate miles (b) Give upper and lower estimates for the distance Roger ran in total during the entire hour and a half. lower estimate upper estimate miles miles (c) How often would Jeff have needed to measure Roger's speed in order to find lower and upper estimates within 0.1 mile of the actual distance he ran? Jeff would need to measure every minutes Enter a fraction, integer, or exact decimal. Do not approximate.
