Let W be the amount of water, in gallons, in a bathtub at time t, in minutes.

(a) What are the meaning and units of dW/dt?

(b) Suppose the bathtub is full of water at time t₀, so that W(t₀) > 0. Subsequently, at time tp > t₀, the plug is pulled. Is dW/dt positive, negative, or zero:

(i) For t₀ p?

(ii) After the plug is pulled, but before the tub is empty?

(iii) When all the water has drained from the tub?
