Incorrect. Using the formula $\displaystyle{r}=\frac{{W}}{{t}}\usepackage{cmbright}\Huge\$ , the rate of the big leak can be expressed as $\displaystyle\frac{{1}}{{x}}\usepackage{cmbright}\Huge\$ (where x=the amount of time it takes this leak to empty the tank) and the rate of the small leak can be written as $\displaystyle\frac{{1}}{{{5}{x}}}\usepackage{cmbright}\Huge\$ . At what rate was the tower emptying?
