Hi there!
The answer is:

-40i is the answer.
40 pages = 80 minutes
210 pages = ? minutes
Well, take the first fact; 40 pages in 80 minutes and use it to find how many pages per minute.
40/80=1/2
1/2 pages = 1 minute
1 page = 2 minutes

210*2=420
420 minutes = 7 hours
210 pages = 7 hours
Hope this helped :)
