Joselyn is a manager at a sign painting company. She has three painters, Allen, Brianne, and Charles. Allen can complete a large project in 16 hours. Brianne can complete the same sized project in 18 hours. Charles is new, so no one knows how long it will take him.

Joselyn assigns them all a large project to complete together. Explain to Joselyn how this project can tell her how long it would take Charles if he worked by himself. Use complete sentences.

Allen: 1 / 16
Brianne: 1 / 18
Charles: 1 / x

1 / 16 + 1 / 18 + 1 / x

anonymous · Answer

Joselyn would be able to tell how long it would take Charles if he worked by himself by figuring out the time it takes allen and brianne to complete the project together. You would then subtract the time it takes charles helping them to complete the project  and then you should know how long it takes charles by himself
