Draw rectangles on this graph to help you underestimate the total distance traveled by the runner during the rst half hour. What underestimate did you obtain? miles Draw rectangles on this graph to help you overestimate the total distance traveled by the runner during the rst half hour. What overestimate did you obtain? miles Draw rectangles on this graph to help you underestimate the total distance traveled by the runner during the whole time.
