SUMMARY
The problem involves a tank initially containing 40 gallons of pure water, into which a solution with a concentration of 1 gram of salt per gallon is added at a rate of 3 gallons per minute. The solution drains out at the same rate, leading to a dynamic situation where the quantity of salt, Q(t), changes over time. To solve this, one must set up a differential equation based on the rates of salt entering and leaving the tank, considering the concentration of salt in the well-mixed solution.
