Answer:
2.22 hours
Explanation:
If Sally can paint the office by herself in 5 hours, we can say that in one hour she paints 1/5 of the office.
On the other hand, Lucy paints the office in 4 hours, which means that, in 1 hour she paints 1/4 of the office.
Therefore, to know how much they would paint per hour working together, we are going to sum up the fractions they paint per hour:
![\frac{1}{5} +\frac{1}{4}=\frac{4+5}{20} =\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2B%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B4%2B5%7D%7B20%7D%20%20%3D%5Cfrac%7B9%7D%7B20%7D)
Therefore, working together they will paint
of the office in one hour.
Now we can establish a rule of three: if they paint 0.45 of the office in 1 hour, how long (x) will it take them to paint 1.0 of the office?
![1- 0.45\\x-1](https://tex.z-dn.net/?f=1-%200.45%5C%5Cx-1)
And therefore ![x = \frac{1}{0.45}=2.22](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B0.45%7D%3D2.22)
Therefore, it will take them 2.22 hours to paint the office working together.
