60 Pages

Explanation:

40 Pages in 60 Minutes is the rate.

The proofreader can read 20 Pages in 30 Minutes because of the two equations:
40/2=20
60/2=30.

Multiply the numbers by 3.

20*3=60
30*3=90

We got the Minutes category up to 90, and now you can see that at 90 Minutes, the proofreader can read 60 Pages.

Yay!
