1. In a large tank there are 1000 gallons (gal) of water with a concentration of 1 pound (lb) per gallon of a pollutant. Water with a concentration of 0.15 lb/gal flows in at a rate of 5 gal/min (gallons per minute). At the same time, water flows out at the same rate through an outlet at the bottom. (Assume that the incoming solution is perfectly mixed in the tank at all times.) When will the concentration of pollutant decrease under 0.3 lb/gal?
