Question

Carla can read 18 pages in 25 minutes. How long will it take for her to read 76 pages?

Answer 1

It would take 106 minutes rounded to the nearest minute to read 76 pages.

Explanation:

The ration of time to pages is: `25:18` which is the same as `25/18`

We need to how many minutes, let's call it `m`, it takes to read `76` pages so we can write:

`25/18 = m/76`

Solving for `m` gives:

`76 * 25/18 = 76 * m/76`

`1900/18 = cancel(76) * m/cancel(76)`

`m = 105.6`
