.
Use the proportion


    180%2F4.5 = 3420%2Fx


to find the unknown time in minutes under the question.


From the proportion,  x = %284.5%2A3420%29%2F180.


Use your calculator to get the number.

The proportion (*) expresses the fact (the assumption) that the rate of printing is THE SAME in both cases.
