Answer:

10.26secs

Step-by-step 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
