We can solve this problem by setting up a proportion.
The ratio of pages read to time taken is the same for both Brian and you.
For Brian, the ratio is 80 pages / 2 hours = 40 pages/hour.
Let's call the number of pages you can read in 3.5 hours "x".
So, the ratio for you is x pages / 3.5 hours.
Setting up the proportion:
40 pages/hour = x pages / 3.5 hours
To find x, let's cross multiply:
40 * 3.5 = x
x = 140
Therefore, you can read 140 pages in 3.5 hours.
The answer is (D) 140 pages.
