For time, t, in hours, 0 g t g 1, a bug is crawling at a velocity, v, in meters/hour given by 1 \":8_+t' Use At = 0.2 to estimate the distance that the bug crawls during this hour. Use left- and right-hand Riemann sums to find an overestimate and an underestimate. Then average the two to get a new estimate. underestimate = overestimate = average = {for each, include lunjts}
