To find out how many pages Brian can read in 3.5 hours, we can set up a proportion:
Pages read / Time = Pages read / Time
80 / 2 = x / 3.5
Cross-multiplying, we get:
2x = 80 * 3.5
2x = 280
Dividing both sides by 2, we find:
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
To find out how many pages Brian can read in 3.5 hours, we can use a proportion.
Since Brian can read 80 pages in 2 hours, we can set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we cross multiply:
2 hours * x pages = 80 pages * 3.5 hours
2x = 280
Dividing both sides of the equation by 2, we get:
x = 140
Therefore, Brian can read 140 pages in 3.5 hours. So the correct answer is 140 pages.

Since Brian can read 80 pages in 2 hours, we can set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To find x, we can cross multiply:
2 hours * x pages = 80 pages * 3.5 hours
Rearranging the equation, we have:
2x = 280
Dividing both sides by 2, we get:
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
