Gillian Lucero · Answer 1

6 minutes

Step-by-step explanation:

Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.

If they work together, they will be checking at a combined rate of:

1/10 + 1/15 = [3 (1) + 2 (1) ]/30

= 5/30 = 1/6

Their combined rate is 1/6 which means they check one set in 6 minutes
