To find out how many pages Brian can read in 3.5 hours, we can set up a proportion. We know that Brian can read 80 pages in 2 hours. Let's set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross-multiply and divide:
2 * x = 80 * 3.5
2x = 280
x = 280 / 2
x = 140 pages
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. We know that Brian can read 80 pages in 2 hours, so we can set up the proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross multiply and divide:
80 * 3.5 = 2 * x
280 = 2x
Divide both sides by 2:
x = 280 / 2
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
