Final answer:

To complete the driveway from start to finish, it takes 24 hours.

Step-by-step explanation:

To find the time it takes to complete the driveway, we can use a proportion. Let x represent the time it takes to complete the driveway from start to finish. We can set up the proportion: 6 hours is to 30 feet as x hours is to 120 feet. We can cross multiply and solve for x:

  1. 6 hours * 120 feet = 30 feet * x hours
  2. 720 = 30x
  3. x = 24


Therefore, it takes 24 hours to complete the driveway from start to finish.
