Do tests over minutes. 9/22=63/x and cross multiply to solve. 63 times 22 is 1386. Divide that by 9. That equals 154. It took Craig 154 minutes to grade 63 tests.

It will take him 110 minutes.
If he grades 9 tests every 22 minutes, this means that 63 tests/ 9 tests = 7 times
This means that he needs to do it 5 times in order to grade all of the tests.
7 X 22 min (amount of time needed to grade 9 tests)
154 min
or 2 hours 34 min
