Using the rates, it is found that it would take you 8.57 hours to design the website working alone.
The together rate is the sum of each separate rate.
In this problem:
Then:
[tex]\frac{1}{12} + \frac{1}{x} = \frac{1}{5}[/tex]
[tex]\frac{x + 12}{12x} = \frac{1}{5}[/tex]
[tex]12x = 5(x + 12)[/tex]
[tex]12x = 5x + 60[/tex]
[tex]7x = 60[/tex]
[tex]x = \frac{60}{7}[/tex]
[tex]x = 8.57[/tex]
It would take you 8.57 hours to design the website working alone.
