Initially a tank is filled up with 150 gallons of water in which 300 lb of salt is dissolved. Brine with concentration of 1 lb/gal enters the tank at a rate of 5 gal/min. The solution in the tank is kept well-stirred and flows out of the tank at a rate of 3 gal/min. (a) Find the minimum amount of salt in the tank. (b) Find the time taken to reach the minimum amount.
