To find out how many pages Brain can read in 3.5 hours, we can set up a proportion:
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross multiply:
2 hours * x pages = 80 pages * 3.5 hours
2x = 280
x = 280 / 2
x = <<140=140>>140
Therefore, Brain can read 140 pages in 3.5 hours.
Brain can read 80 pages in 2 hours. how many pages can he read in 3.5 hours?
