A computer printer produced 176,400 lines in a given day. If the printer was in operation for seven hours during the day, how many lines did it print per minute?

• 7hrs = 420 mins
  1 min = 176400/420 = 420
  so 420 lines/min

  For one hr,176400/24=7350 lines
  For 7 hrs,7350*7=51450
  for one min,51450/(7*60)=122.5
