Answer :

Sue reads at a rate of 40 pages in 80 minutes, which translates to 2 minutes per page. Multiplying this rate by the 210 pages she needs to read, it will take Sue 420 minutes, or 7 hours, to read the entire amount.

The student has stated that Sue reads 40 pages in 80 minutes and is asking how long it will take her to read 210 pages. To solve this, we first calculate Sue's reading rate. Given her current rate of 40 pages in 80 minutes, we find that she reads one page in 2 minutes (80 minutes \/ 40 pages = 2 minutes/page). Now, to find out how long it will take to read 210 pages, we simply multiply the number of pages by the time it takes to read one page:

210 pages x 2 minutes/page = 420 minutes.

Therefore, it will take Sue 420 minutes to read 210 pages. To convert this to hours, we divide by 60 (the number of minutes in an hour):

420 minutes \/ 60 minutes/hour = 7 hours.

So, Sue will need approximately 7 hours to complete her reading of 210 pages.
Set up a ratio 40 pages / 80 minutes
This can be reduced to 1 page in 2 minutes.
210 pages will take 410 minutes.
