Answer: 18 pages
======================================
Explanation:
Trey reads 10 pages in 25 minutes, which means we have the ratio
10 pages: 25 minutes
Divide each part of the ratio by 25
10 pages: 25 minutes
10/25 pages: 25/25 minutes
0.4 pages: 1 minute
So Trey's unit rate is 0.4 pages per minute. In one minute, Trey reads 0.4 of a page
Now multiply both sides of the last ratio by 45
0.4 pages: 1 minute
45*0.4 pages: 45*1 minute
18 pages: 45 minutes
Which is why the answer is 18 pages
It takes Trey 45 minutes to read 18 pages
Or in other words, Trey reads 18 pages in 45 minutes.
