Question
10) The distance an new hiker travels is described by s(t) = 3vt + 5 kilometers, where t is in hours.
(a) Find the average velocity of the hiker from t = 2 hours to t = 4 hours.
(b) Compute the instantaneous velocity of the hiker, v(t), using the definition of the derivative (do NOT use
differentiation rules)(Notice that we are using t's instead of x's).
(c) At what time is the velocity of the hiker equal to 0.2? Justify your answer (if you did not finish (b),
explain how you would to do this problem).
