A tank initially holds 100 gal of a brine solution containing 20 lb of salt. At t = 0, fresh water is poured into the tank at the rate of 5 gal/min, while the well stirred mixture leaves the tank at the same rate. After how many hours will the tank be emptied of salt? Select the correct response: as "t" approaches infinity 30 hours O 20 In (t) hours as "t" reaches maximum value O none of these cannot be determined
