Question

A copy machine makes 19 copies in 3 minutes and 15 seconds. How many copies does it make per minute?

Answer 1

5 copies

Explanation:

answer x 60

Answer 2

10.26secs

Explanation:

Let's start by converting 3minutes 15seconds to second

How

60secs=1min

Xsec=3mins

Let's cross multiply

x=60×3

X=180secs

180+15

195secs

So 19 copies=195 secs

1copy=x sec

Cross multiply

19x=1×195

19x=195

Divide both sides by 19

X=10.26secs
