To find out how many pages Brian can read in 3.5 hours, we can use the concept of proportions.
We know that Brian can read 80 pages in 2 hours. Let's 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
This simplifies to:
2x = 280
Now, divide both sides of the equation by 2 to solve for x:
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 information given. 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 this proportion for x, we can cross-multiply and then divide:
80 * 3.5 = 2 * x
280 = 2x
Divide both sides of the equation by 2:
280 / 2 = x
x = 140
Therefore, Brian can read 140 pages in 3.5 hours.
