(1 point) For time, t, in hours, 0 S t S 1, a bug is crawling at avelocity, U, in meters/hour given by 9 U=. 4+: 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: 417028111 42591me .421472m (for each, include units) overestimate = average =
