  1. This 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.
