A computer printer produced 172,800 lines in a given day. If the printer was in operation for eight hours during the day, how many lines did it print per second?

• 172800/28800=6 lines/sec
  
  convert 8 hours to sec=28800 sec

• 1 day=24hrs
  24 -------------- 172800
  8 -------------- x
  cross multiply,
  x=(172800*8)/24
  x=57600

• Day =24hrs
  24hrs=172800
  1hr=7200
  As it Worked for only 8 hours
  8hrs=7200*8
  =57600
  For Eight Hours it Printed 57600 lines
  Then for 1sec=57600/8*60*60
  =57600/28800
  =2 (It prints 2 lines per sec)
