A machine can produce 27 inches every 3 minutes. How many feet of ribbon can the machine make in one hour? Explain
27(60/3) = ________ inches
Divide the number of inches by 12 to find the number of feet.
27
To figure out how many feet of ribbon the machine can make in one hour, we need to determine the number of inches it produces in one hour and then convert that into feet. Here's how you can calculate it:
1. Determine the number of inches produced in one minute:
Since the machine produces 27 inches every 3 minutes, we can divide 27 by 3 to find out how many inches it produces in one minute.
27 inches / 3 minutes = 9 inches.
2. Calculate the number of inches produced in one hour:
Since there are 60 minutes in an hour, we can multiply the number of inches produced in one minute by 60 to find out how many inches the machine would produce in one hour.
9 inches/minute x 60 minutes/hour = 540 inches.
3. Convert inches to feet:
Since there are 12 inches in a foot, we can divide the number of inches produced in one hour by 12 to convert it into feet.
540 inches / 12 inches/foot = 45 feet.
Therefore, the machine can produce 45 feet of ribbon in one hour.
