Question

Working together, Shannon and actor can install a tile floor in six hours. It would take Sean nine hours to do the job alone. What is the value or the part of the tile floor that Shannon could install in one hour?

a) 1/9
b) 1/6
c) 1/8
d) 1/15

Answer 1

Shannon could install 1/6 of the tile floor in one hour.

Step-by-step explanation:

To find the value or part of the tile floor that Shannon could install in one hour, we can use the formula:

Part of job done in one hour = 1 / (Time taken to complete the job together)

Shannon and Sean can complete the job together in 6 hours, so:

Part of job done in one hour = 1 / 6

Hence, the value or part of the tile floor that Shannon could install in one hour is 1/6 (option B).
