Question

Which rate is greater? 18 pages in 36 minutes or 20 pages in 30 minutes. Explain your resoning

Answer 1

The second example is a greater rate of reading. 

In order to come to that conclusion, I didn't do any figuring, ciphering,
numerating, or calculating of any kind.  I just sat there and looked at
the question.  I noticed that the second example is more pages than
the first one, but done in less time than the first one.  So I know that
it must be a greater rate of cranking out the pages.

Answer 2

The first rate is 18/36 = 0.5 While the second rate is 20/30 = 0.6666666 So the second rate is greater.
