The number of hours that it'll take both printers to do the job is 2.4 hours.
<em>Number of hours used by printer A = 6 hours</em>
<em>Number of hours used by printer B = 4 hours </em>
<em />
Therefore, the number of hours that'll be used by both printers will be calculated thus:
1/6x + 1/4x = 1
Using 12 as the LCM
2x + 3x = 12
5x = 12
Divide both side by 5
5x/5 = 12/5
x = 2.4 hours
