Calculator active. Mr. Kelly and Mr. Sullivan are doing a morning speed-walk race going down a straight and Mr. Sullivan's 16500 t2-5t+74.33 street. For 0 ≤ t ≤ 20, Mr. Kelly's velocity at time t is given by K(t) = velocity at time t is given by S(t) = 41t³e-0.6t. Both K(t) and S(t) are positive for 0 ≤ t ≤ 20 and are measured in yards per minute, and t is measured: minutes. Mr. Kelly has a 5 yard head-start at t = 0, and is ahead of Mr. Sullivan for the entire time 0 ≤ t ≤ 20. b. At time t = 7, is Mr. Kelly speeding up or slowing down? Give a reason for your answer. c. Is the distance between Mr. Kelly and Mr. Sullivan at time t = 7 increasing or decreasing? Give a reason for your answer.

14. Calculator active. Mr. Kelly and Mr. Sullivan are doing a morning speed-walk race going down a straight
street. For 0 ≤ t ≤ 20, Mr. Kelly's velocity at time t is given by K (t)
and Mr. Sullivan's
velocity at time t is given by S(t) = 41t³e-0.6t. Both K(t) and S(t) are positive for 0 ≤ t ≤ 20 and are
measured in yards per minute, and t is measured in minutes. Mr. Kelly has a 5 yard head-start at t = 0, and is
ahead of Mr. Sullivan for the entire time 0 ≤ t ≤ 20.
b. At time t = 7, is Mr. Kelly speeding up or slowing down? Give a reason for your answer.
c. Is the distance between Mr. Kelly and Mr. Sullivan at time t = 7 increasing or decreasing? Give a reason
for your answer.
d. What is the maximum distance between Mr. Kelly and Mr. Sullivan over the time interval 0 ≤ t ≤ 20?
