Brian is conducting surveys for a research paper. each survey takes him about 10 minutes to complete, so he can get 6 done per hour. at this rate, how many hours will it take brian to complete 30 surveys? (let h stand for the number of hours.)

5 hours

Step-by-step explanation:

Let h stand for the number of hours

Because it takes him 10 minutes to complete 1 survey so 30 surveys would take him:

1 survey = 10 minutes

1 * 30 surveys = 10*30

30 surveys = 300 minutes

1 hour have 60 minutes

So it would take him:

h = 300 / 60

h = 5

So it would takes him 5 hours to finish 30 surveys
