Please solve this question ASAP in fully details and explaination.

Suppose that three parameters of a gas: Pressure P, volume V, and temperature T at all times t are related by the equation PV : (IT, where a = 8 kPa litres/kelvin is a constant. Suppose that we start decreasing the pressure at a rate of 4 kPa/min and increase the temperature at a rate of 5 kelvin/min. How quickly is the volume changing when the temperature reaches 290 kelvin and the presure at the moment is 200 kPa? The volume is changing at a rate of = [j litres/min
