Correct. The equation $\displaystyle\frac{{1}}{{x}}+\frac{{1}}{{5}}{x}=\frac{{1}}{{60}}\usepackage{cmbright}\Huge\$ represents the rate of the big leak $\displaystyle{\left(\frac{{1}}{{x}}\right)}\usepackage{cmbright}\Huge\$ , the small leak $\displaystyle{\left(\frac{{1}}{{{5}{x}}}\right)}\usepackage{cmbright}\Huge\$ , and the rate at which the tower emptied $\displaystyle{\left(\frac{{1}}{{60}}\right)}\usepackage{cmbright}\Huge\$ .
