Mathematics - Application of Derivative Question with Solution | TestHub

The volume $V$ and depth $x$ of water in a vessel are connected by the relation $\mathrm{V}=5\mathrm{x}-\frac{{\mathrm{x}}^2}{6}$ and the volume of water is increasing , at the rate of $5{\mathrm{cm}}^3/\sec$, when $\mathrm{x}=2\mathrm{cm}$. The rate at which the depth of water is increasing, is
