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:
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?

Today, people are warming up to the idea of education being instrumental in an all-rounded development of a person instead of just being a course to earn degrees and monetary success in life. It is broadly accepted that learning plays a key role in shaping one’s personality.
We get to know the world around us through education. It helps us build opinions and develop a perspective of looking at life. It forms the groundwork of any society and is one of the most important elements in addressing social problems.
A social problem is an issue or a factor within the society that affects the real world. Gender inequality, poverty, child abuse, unemployment, racism and discrimination based on religion are some of the many social issues prevailing in our society.
As a child, we make sense of the world in terms of right and wrong, good and bad. But as we grow up, we tend to understand the world in more complex ways. School is the foremost source of knowledge. From the early stages, we are exposed to different cultures and traditions. We also gain communication skills, we get to interact with different kinds of people, we are introduced to several opportunities and interactive projects.
