The graph to the right shows the rate of inhalation of oxygen (in liters per minutes) by a person riding a bicycle very rapidly for 5 minutes. Estimate the total volume of oxygen inhaled in the first 10 minutes after the beginning of the ride. Use rectangles with widths of 1 minute. Liters per minute 0 1 2 3 4 5 6 7 8 9 10 Minutes Using the left endpoints, the total volume is about |liters. Using the right endpoints, the total volume is about |liters. (Type integers or decimals rounded to the nearest tenth as needed.)
