Well if there is 225 lose papers to a single inch in order to find out how many loose papers the clerk has all together we will have to multiply 125 x 225.
125 x225 = 28125
The clerk has to sort 28125 papers in total.
Now she can sort 7 papers in a minute so now we divide 28125 by 7.
28125/7 = a rough estimate of 4018 minutes
The clerk will take about 66 hours and 58 minutes
Or 67 hours if you want to estimate
