**MathMate**, Friday, August 3, 2012 at 10:29amThis must be a problem from an older book. Printers today do not print a line at a time, but let's assume that's the case (for a "matrix" printer).

80 characters / second

2400 characters / page

means

2400/80=30 seconds / page

= 30/60= 1/2 minute / page

If we have to print M pages, time taken is therefore

M(1/2) = M/2 minutes.
