Kelly is reading a 1,248-page book. During the past 4 days she has read 384 pages. At this rate, how many more days will it take her to complete the book?

Respuesta :

Kelly needs 9 more days to complete the entire book

Step-by-step explanation:

Given:

Total number of pages Kelly has to read=1248 pages

Number of pages read in the past 5 days=384

To find:

The number of days Kelly needs to read the book?

Solution:

[tex]\text {The rate at which kelly reads the pages}=\frac{\text { (Total no.of pages she has read) }}{\text { Total no.of days }}[/tex]

Substituting the values we get,

[tex]\begin{array}{l}{\text { The rate at which Kelly reads the pages }=\text { (Total no. of pages she has read) / Total no. of }} \\ {\text { days }}\end{array}[/tex]

[tex]\text { The rate at which Kelly reads the pages }=\frac{384}{4}[/tex]

The rate at which Kelly reads the pages=96 pages per day

[tex]\text { The no. of days required }=\frac{\text { total pages }}{\text { rate of reading }}[/tex]

[tex]\text { The no. of days required }=\frac{864}{96}[/tex]

The no. of days required  = 9 days

Thus it takes 9 days to complete her book.
