First, convert 2 hours into minutes. You know that there are 60 minutes in 1 hour. Thus, 2 hours = 120 minutes.
Set a ratio to solve for x, the number of pages Tim can read in 2 hours (120 minutes). The numerator represents the number of pages read, and the denominator represents the amount of time elapsed.

Use the cross-multiplying method, where you multiply x by 120 and 48 by 100.

To isolate x, divide both sides of the equation by 120.
The answer is x = 40.
Therefore, Tim can read 40 pages in 48 minutes.
Hope this helps! :)
