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

Hope this help you :3

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
