7. The function plotted below shows the velocity v(t) of an object in miles per hour asa function of time t. (3 2 10 (a) Estimate the distance traveled from t-0 tot-10 hours using a left-sum with n-5 rectangles. (b) Estimate the distance traveled fromt-0 tot-10 hours using a right-sum with n-5 rectangles. (c) Try to improve the above estimates by averaging them. (d) Estimate the distance traveled from t-0 tot-6 hours using a left-sum with (e) Estimate the distance traveled from t- 0 to t-6 hours using a left-sum with (f) Which of the previous two estimates do you think is a more accurate representation (g) What are the units ofv(t) dt? n-3 rectangles. n-6 rectangles. of the true area?
