Zach can read 7 pages of a book in 5 minutes. At this rate, how long will it take him to read the entire 175 page book?

Set up a proportion of pages to minutes where m is the number of minutes needed to read 175 pages:
7/5 = 175/m

To solve this proportion, we type it in our search engine and we get:
m = 125 minutes or 2 hours and 5 minutes
