To determine how many pages Brian can read in 3.5 hours, we first find his reading rate.
Brian can read 80 pages in 2 hours, so his reading rate is:
\[
\text{Reading rate} = \frac{80 \text{ pages}}{2 \text{ hours}} = 40 \text{ pages per hour}
\]
Now, to find out how many pages he can read in 3.5 hours, we multiply his reading rate by the time:
\[
\text{Pages read in 3.5 hours} = 40 \text{ pages per hour} \times 3.5 \text{ hours} = 140 \text{ pages}
\]
So, Brian can read **140 pages** in 3.5 hours.
