Related Rates Conical Tank

Water is pumped into an inverted conical tank at a rate of $3\;m^3/min$. The tank has a height of 5 meters and a radius of 2 meters at the top. The volume of water in the tank is given by $V=\frac{1}{3}\pi r^2 h$, where $r$ is the radius of the water’s surface and $h$ is the height of the water. For this tank, the relationship between the radius and height is $r=\frac{2}{5}h$. At what rate is the height of the water increasing when the water is 3 meters deep?
