4. A tank is initially filled with 300 gallon of salt solution containing 1 kg of salt per gallon. A brine containing 3 kg of salt per gallon runs into the tank at the rate of 10 gallons/minute, and the mixture, assumed to be kept uniform by stirring, runs out at the same rate. Find the amount of salt in the tank at any time t, and determine how long it will take for this amount to reach 500 kg.
