Charlie reads quickly. He reads 1\dfrac371 7 3 ​ 1, start fraction, 3, divided by, 7, end fraction pages every \dfrac23 3 2 ​ start fraction, 2, divided by, 3, end fraction minutes. Charlie reads at a constant rate. How many pages does he read per minute?

Respuesta :

Answer:

The number of pages he will read in one minute is:

        [tex]2\dfrac{1}{7}\ \text{pages}[/tex]

Step-by-step explanation:

It is given that:

Charlie reads [tex]1\dfrac{3}{7}\ \text{pages}[/tex] in every [tex]\dfrac{2}{3}\ \text{minutes}[/tex].

We know that:

[tex]1\dfrac{3}{7}=\dfrac{10}{7}[/tex]

This means that:

Charlie reads [tex]\dfrac{10}{7}\ \text{pages}[/tex] in every [tex]\dfrac{2}{3}\ \text{minutes}[/tex].

This means that:

[tex]\text{In}\ \dfrac{2}{3}\ \text{minutes he reads}\ \dfrac{10}{7}\ \text{pages}\\\\\text{Hence}[/tex]

[tex]\text{In}\ 1\ \text{minute he will read}\ \dfrac{\dfrac{10}{7}}{\dfrac{2}{3}}\ \text{pages}[/tex]

[tex]\text{In}\ 1\ \text{minute he will read}\ \dfrac{10\times 3}{7\times 2}\ \text{pages}[/tex]

Hence,

[tex]\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}[/tex]

Hence,

[tex]\text{In}\ 1\ \text{minute he will read}\ \dfrac{15}{7}\ \text{pages}[/tex]

[tex]\text{In}\ 1\ \text{minute he will read}\ 2\dfrac{1}{7}\ \text{pages}[/tex]
