A copy machine makes 104 copies in 3 minutes and 15 seconds. how many copies does it make per minute
Gnesinka [82]

Answer:

<h2>32 copies</h2>

Step-by-step explanation:

First convert 3 minutes and 15 seconds into minutes by converting 15 sec to min and add it to 3min

60 sec = 1min

15 sec = 15 / 60 × 1 min

= 0.25min

Add it to 3min

3min + 0.25min = 3.25 min

<u>We use ratio and proportion</u>

3.25min = 104 copies

1 min = 104× 1/ 3.25

= 104 / 3.25

= 32

The final answer is 32 copies

Hope this helps you.
