Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.
The together rate is the sum of each separate rate.
In this problem, the rates are:
Hence:
[tex]\frac{1}{12} + \frac{1}{x} = \frac{1}{8}[/tex]
[tex]\frac{x + 12}{12x} = \frac{1}{8}[/tex]
[tex]12x = 8x + 96[/tex]
[tex]4x = 96[/tex]
[tex]x = \frac{96}{4}[/tex]
[tex]x = 24[/tex]
