Trey reads 10 pages in 25 minutes. At the rate, how many pages will he read in 45 minutes?
neonofarm [45]
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.
