4 Select the correct answer. The displacement of a train starting from a stop is given by the equation s(t) = 8vt + 1meters. Estimate the instantaneous velocity of the train at t= 9 seconds by considering the average velocities over the intervals [8.5, 9], [8.7, 9], [8.9, 91, [8.99, 9], [9, 9.01], [9, 9,1], [9, 9.3], and [9, 9.5].
