A tank initially contains 17 pounds of salt dissolved in 450 gallons of water. Starting at to = 0, water that contains 2/5 pounds of salt per gallon is poured into the tank at a rate of 10 gallons per minute and the mixture is drained from the tank at the exact same rate. Assume the tank is uniformly mixed at all times. Use this information to answer the following questions. a) Find a differential equation for the quantity of salt in the tank at time t > 0 b) Solve the differential equation from part (a) to find Q (t)

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
