Hello,
We need the amount done in one minute which is
1/12 and 1/10 so we have 1/12 + 1/10 = 1/t
Multiplying by 60t (common denominator) giving us 5t + 6t = 60 so 11t = 60 and then t = 60 /11 or 5 and 5/11 minutes.
Hope This Helps!

you sure need help
(just as you said)
the way you wrote it the copier is NOT involved
so anyone that included the copier did not read the question
and gets nil points
