Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.
<h3>What is the together rate?</h3>
It is the sum of each separate rate.
In this problem, the rates are given as follows:
Hence:
![\frac{1}{9} + \frac{1}{x} = \frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D%20%2B%20%5Cfrac%7B1%7D%7Bx%7D%20%3D%20%5Cfrac%7B1%7D%7B7%7D)
![\frac{x + 9}{9x} = \frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20%2B%209%7D%7B9x%7D%20%3D%20%5Cfrac%7B1%7D%7B7%7D)
![9x = 7x + 63](https://tex.z-dn.net/?f=9x%20%3D%207x%20%2B%2063)
2x = 63
x = 31.5.
It would take the assistant 31 hours and 30 minutes to do it alone.
