Question

Jayne is on page 54 of a book at a rate of 300 words per minute it will take her 2.8 hours to read 100 pages if her book is 312 pages how long will it take her to finish the rest of the book round to the nearest hundredth of an hour

Answer 1

7.22 hours

Explanation:

To find out how long it will take Jayne to finish the rest of the book, we can set up and solve a ratio.

If Jayne is on page 54 of a book, and her book is 312 pages long, then the total number of pages left to read is:

`312 - 54 = 258 \sf \;pages`

Given it takes Jayne 2.8 hours to read 100 pages, we can set up a ratio of hours to pages, where x is the number of hours it takes to read the remaining 258 pages:

`(x)/(258)=(2.8)/(100)`

Solve for x:

`(x)/(258)=0.028`

`(x)/(258)\cdot 258=0.028\cdot 258`

`x=7.224`

Therefore, it will take Jayne approximately 7.22 hours to finish the rest of the book (rounded to the nearest hundredth of an hour).
