Joe rides his bicycle an average of 17 mph. The distance Joe rides d (t) (in mi) is given by d (t) =17 t, where * is the time in hours that he rides. (a) Evaluate d (5) and interpret the meaning. (b) Determine the distance Joe travels in 48 min. Give the exact answer. Do not round. Part 1 of 2 (a) d (5) = 85 . Thus, Joe travels 85 mi in 5 hours. X Part: 1 / 2 Part 2 of 2 9 (b) Joe travels 13 15 mi in 48 min. X 5
