The Chain Rule & Implicit Differentiation · Medium problem

For a certain gas, $P = \dfrac{10T}{V}$ (pressure $P$ in kPa, temperature $T$ in K, volume $V$ in L). At the moment when $T = 300$ and $V = 100$, the temperature is rising at $2$ K/s and the volume is growing at $1$ L/s. Find $\dfrac{dP}{dt}$ in kPa/s.
