(1 point) The velocity graph of a braking car is shown (where velocity is measured in feet per second and time is measured in seconds). Use it to estimate the distance traveled by the car while the brakes are applied. Use n = 3 approximating rectangles in your work. 60 50 40 30 20 10 2 3 4 5 6 Midpoint Approximation Estimate the distance traveled as described above using midpoints. List the midpoints (separated with commas) and then calculate the approximation M3. Midpoints are: M3
