In order to get how long it takes to install one sheet of drywall, you have to divide 10/8, which would equal 1.25. Now you know how long it will take to install one sheet, so next you would have to multiply 1.25 by 60, and you would get 75 minutes, which is 1 hour and 15 minutes, otherwise known as 1.25 hours.
