Can you please help me find the Left Riemann and the Right Riemann as well as the average of the two

Walt goes for a 12-min walk. His pedometer shows his speed, v(t), in miles per hour, for 1-min intervals. Use L12, R12, and their average to approximate the distance Walt travels. t (min) 0 1 2 3 4 5 6 7 8 9 10 11 12 v(t) (mi/hr) 0 4 5 6 6 4 4 1 2 1 6 6 5 Write the definite integral that represents the exact distance approximated by L12 and R12 distance = L12 = (Round to three decimal places as needed.) R12 = (Round to three decimal places as needed.) The average of L12 and R12, the distance that Walt travels, is (Round to three decimal places as needed.)
