Answer:
20 hours
Step-by-step explanation:
If the machine drilled 72 feet in 24 hours, we can divide 72 by 24 to find out that the machine drilled 3 feet in one hour.
Next, you must find the distance that must be traveled. You can do this by subtracting 72 from 132. You will get 60
So, if the machine drilled at 3 feet per hour, and it needs to drill 60 feet, it will take 20 hours because 60 divided by 3 is 20.
