Question

Working alone, Shayna organ in 9 minutes. Kayla can revarnish the pipe organ in 15 minutes. If they worked together how long would it take them? build a home. Trevon can build the same home in 13 weeks. Find how long it would take them if they worked together same

Answer 1

5.625 minutes to revarnish the pipe organ together.

Explanation:

Given;

Time taken by Shayna to revarnish the pipe organ = 9 minutes

Time taken by Kayla to revarnish the pipe organ = 15 minutes

Now,

In one minute pipe organ revarnished by Shayna =
`\frac{\textup{1}}{\textup{9}}`

In one minute pipe organ revarnished by Kayla =
`\frac{\textup{1}}{\textup{15}}`

Therefore,

Working together total work completed in one minute =
`\frac{\textup{1}}{\textup{9}}+\frac{\textup{1}}{\textup{15}}`

=
`\frac{\textup{8}}{\textup{45}}`

=
`\frac{\textup{1}}{\textup{5.625}}`

hence,

The time taken = 5.625 minutes to revarnish the pipe organ together.
