Hello!

Let's set this problem up as a proportion....

# of pages : # of minutes

x is the number of pages that we DON'T know....

(4/3)/20 = x/150
x = 10 

The number of pages Brian can type in 2.5 hours is 10

I hope this helps! :D

Please vote me for Brainliest if there is a second answer! ^__^

there are 150 minutes in 2.5 hours. And Brian can type 1 and 1/3 pages in 20 minutes. so divide 150 minutes by 20 minutes which is 7.5minute then multiply 7.5 by 4/3 (1 and 1/3) and you get the result 9.999 

He can type 9.99 pages in 2.5 hours
