Question

A copy machine makes 126 copies in 5 minutes and 15 seconds. How many copies does it make per minute?

Answer 1

Answer: 24 copies per minute

Explanation:

First, we will turn minutes and seconds into minutes. To transform seconds into minutes, we divide by 60. Then, we will add on the extra minutes.

(15/60) + 5 = 5.25 minutes

Next, we will find the number of copies per minute (
`(copies)/(minute)`). If we look at the unit rate, we want to divide the number of copies by the number of minutes.

`\displaystyle (copies)/(minute)=(126)/(5.25) = 24.0458\; (copies)/(minute) \approx 24 (copies)/(minute)`
