Question

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.)

Answer 1

5 hours

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

Hope this help you :3
