Casey can install a fountain in a school garden in 20 hours. samuel can install a similar fountain in the same school garden in 30 hours. if they work together, they would take a total of t hours to install the fountain. write an algebraic expression in terms of t for the fraction of the fountain they can install together in one hour. write an equation for t. solve for t to find the total number of hours they would take to install the fountain if they work together.

The required equation is .

They will take 1.2 hour to install the fountain in school if they wirk together.

Step-by-step explanation:

Given: The time taken by Casey to install a fountain in a school= 20 hours

The time taken by Samuel to install the same fountain in school= 30 hours

Let t be the time of installation of fountain if they work together, then we have the following equation:-

Hence, they will take 1.2 hour to install the fountain in school if they wirk together.
