Question

Amanda read 18 pages in 23 minutes. At this rate, how many pages will she read in 45 minutos? I need a clear answer with explanation I have to expose this

Answer 1

35.22 pages

Step-by-step explanation:

If the rate is the same, the ratio of the number of pages to total minutes is constant, so we can write the following equation:

`\frac{\text{pages}}{\text{minutes}}=\frac{p}{45\text{ min}}=\frac{18\text{ pages}}{23\text{ min}}`

Where p is the number of pages that Amanda read in 45 minutes. Solving for p, we get:

`\begin{gathered} (p)/(45)=(18)/(23) \\ (p)/(45)*45=(18)/(23)*45 \\ p=35.22\text{ pages} \end{gathered}`

Therefore, she will read 35.22 pages in 45 minutes.
