Answer :
The apricot printer has a speed of 8, and it prints the document in 4.5 minutes.
Because the sure-fire printer operates at a speed of 12, it needs less time to print the document.
The reduction in time is the ratio 8/12 = 2/3.
Therefore the sure-fire printer prints the document in
(2/3)*(4.5 min) = 3 min.
Answer: 3 minutes
