A copy machine makes 44 copies per minute. How long does it take to make 187 copies?
Ratios and Proportions:
Ratios and proportions can be used to solve certain scenarios. A set ratio needs to be established and then one can find out a missing variable for another ratio by using proportions.
Answer and Explanation:
In this scenario, it is established that a copy machine makes 44 copies in one minute. So in order to find out how long it takes to make 187 copies, a proportion is set up.
44 copies / 1 min = 187 copies / x min
So one multiplies 187 by 1 and then divides by 44 to solve for x.
X then equals 4.25 minutes.
