Question 549362: A rectangular driveway has a length of 20 yards and a width of 6 yards. How long will it take to clean the driveway if it takes 45 seconds to clean one square yard? Answer by TutorDelphia(193) (Show Source):
You can put this solution on YOUR website! The driveway's area is 120 square yards (20*6).
120*45 seconds is 5400 seconds, to figure out minutes, divide by 60 and we get 90 minutes. To figure out hours, we can divide by 60 again and we'll get 1.5 hrs
