4. Tank A initially holds 100 gallons of brine that contains 100 pounds of salt, and tank B holds 100 gallons of water. Two gallons of water enter A each minute, and the mixture, assumed uniform, flows from A into tank B at the same rate. If the resulting mixture, also kept uniform, runs out of B at the rate of 2 gallons per minute, how much salt is in tank B at the end of one hour.
