Problema Solution
A copy machine makes 161 copies in 5 minutes and 45 seconds. How many copies does it make per minute?
Answer provided by our tutors
If you look at the ultimate question -- they want to know "copies per minute".
You have to convert the 5 minutes & 45 seconds to 5.75 minutes.
Then:
161 copies / 5.75 minutes = 28 copies per minute
