Airline travel The following figure shows the position function of an airliner on an out-and-back trip from Seattle to Minneapolis, where s = f 1t2 is the number of ground miles from Seattle t hours after take-off at 6:00 a.m. The plane returns to Seattle 8.5 hours later at 2:30 p.m. a. Calculate the average velocity of the airliner during the first 1.5 hours of the trip 10 t 1.52. b. Calculate the average velocity of the airliner between 1:30 p.m. and 2:30 p.m. 17.5 t 8.52. c. At what time(s) is the velocity 0? Give a plausible explanation. d. Determine the velocity of the airliner at noon 1t = 62 and explain why the velocity is negative.
