A gas in a container changes its volume according to the law, PV = 3 600, where P is the number of units of pressure and V is the number of units of the volume. Given that P is increasing at a rate of 20 units per second at the instant when P = 40, calculate the rate of change of volume at this instant. It would be better if Differentiation is used.
