Atub filled with 50 quarts of water empties at a rate of 2.5 quarts per minute. let w = quarts of water left in the tub and t = time in minutes.

Is there a viable solution when time is 30 minutes? No, the tub will be empty by then. 

A tub filled with 50 quarts of water empties at a rate of 2.5 quarts per minute.

Let w be the quarts of water left in the tub.

Let t be the time in minutes.

So, the equation to model this situation is :

Modelling equation:

This equation is viable only up to when t is 20 minutes. That will give w = 0. More than 20 minutes is not possible.
