Respuesta :

Step-by-step explanation:

Miss K has already graded 10 tests and is grading 9 every hour. We will add keep adding 9 starting from 10.

Mr. T has already graded 22 tests and is grading 7 per hour. We will keep adding 7 starting from 22.

Miss K: 19, 27, 36. ( Took 3 hours to reach 36 tests)

Mr T: 29, 36. (Took 2 hours to reach 36 tests)

It will take Miss K 3 hours and Mr T 2 hours to have graded the same amount of tests (36).

Sorry if I'm wrong
