A pond initially contains 1M gal of water and an unknown amount of an undesirable chemical. Water containing 0.01 gram of this chemical per gallon flows into the pond at a rate of 300 gal/hr. The mixture flows out at the same rate, so the amount of water in the pond remains constant. Assume that the chemical is uniformly distributed throughout the pond. How many days elapsed when the amount of chemical in the pond became 2,300 grams from an amount of 100 grams? 40.2 days O 34.9 days O 29.6 days O 38.7 days
