A tank contains 500 gallons of salt-free water. A brine containing 0.25 lb of salt per gallon runs into the tank at the rate of 5 gal , and the well-stirred mixture runs out at 5 gal. In pounds per gallon what is the concentration of salt in the tank at the end of 10 minutes? (Round your answer to four decimal places.)
