A river was found to be contaminated with toxins at a concentration of 0.006 grams per cubic meter near a mine tailings pond. 1500 meters away, the concentration was found to be 0.004 grams grams per cubic meter. Assume the concentration drops off linearly going downstream, and it is uniform over the 50 square meter cross section. How many grams of toxins do you estimate have leaked from the tailings pond? a. 675 grams b. 650 grams c. 700 grams d. 625 grams
