#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!
