To find out how many pages Brian can read in 3.5 hours, we can set up a proportion. The ratio of pages read to hours is the same, so we can write:
80 pages / 2 hours = x pages / 3.5 hours
To find x, we can cross multiply and solve for x:
2 * x = 80 * 3.5
2x = 280
x = 280 / 2
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 set up a proportion using the ratio of pages to time.
80 pages / 2 hours = x pages / 3.5 hours
To solve for x, we can cross-multiply and then divide:
2 hours * x pages = 80 pages * 3.5 hours
2x = 280
Dividing both sides by 2, we get:
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 set up a proportion using the given information. 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 solve for X:
2 hours * X pages = 80 pages * 3.5 hours
2X = 280
Dividing both sides by 2, we get:
X = 140
Therefore, Brian can read 140 pages in 3.5 hours.
