• The graph of the velocity of a braking car is shown. Use this graph and a midpoint sum with six equal subintervals to estimate the distance traveled (in feet) by the car while the brakes are applied. The t v coordinate plane is given. The units of t are seconds and the units of v are ft/s. A curve entirely in the first quadrant goes down and right becoming less steep, going through the following approximate points. (0.5, 71.25) (1.5, 50) (2.5, 35) (3.5, 22.5) (4.5, 12.5) (5.5, 5)
