Question

A machine can produce 27 inches of ribbon every 3 minutes. How many feet of ribbon can the machine produce in one hour? Explain.

Answer 1

First, you have to know how many times you can make 27 inches of ribbon in an hour by dividing 60 by 3. (60 minutes = 1 hour) You get 20, so you can make 27 inches of ribbon 20 times in an hour. Now multiply 20 x 27 to get 540, so you can make 540 inches of ribbon in an hour. To get feet, divide 540 by 12. (12 inches = 1 foot)  So your answer will be 45 feet of ribbon.
