( 10 points) The table below shows the speed of a car measured every 10 minutes (
(1)/(6)hour)for an hour. \table[[Time ( hour),0,
(1)/(6),
(2)/(6),
(3)/(6),
(4)/(6),
(5)/(6),1],[speed (mile per hour),0,30,45,42,48,50,54]] (a) Use a midpoint-sum with
n=3to estimate the distance traveled. (b) Find an upper estimate the total distance traveled by using
n=6.
