35. A tank contains 10 lb of salt dissolved in 30 gal of water. Suppose 2 gal of brine containing 1 lb of dis- solved salt per gallon runs into the tank every minute and that the mixture (kept uniform by stirring) runs out at the same rate. a. Find the amount of salt in the tank at time t. b. How long does it take (to the nearest second) for th tank to contain 15 lb of salt?
