The volume, \(V\text{ m}^3\), of a given mass of gas is inversely proportional to the pressure, \(P\text{ N/m}^2\).

When the volume is \(5\text{ m}^3\), the pressure is \(120\text{ N/m}^2\).

Write down an equation connecting \(V\) and \(P\).

Find the pressure of the gas when the volume is \(24\text{ m}^3\).
