We will first find the number of sheets in 125 inches. If there are 225 sheets in an inch, then there are also 28,125 sheets in 125 inches because
225 sheets/inch × 125 inches = 28,125 sheets.
Now, we will find how long it will take her to file 125 inches of loose sheets.
If a clerk can sort 375 sheets per hour, then she will take 75 hours to sort 28,125 sheets because
28,125 sheets ÷ 375 sheets/hour = 75 hours
Therefore, a clerk can sort 125 inches of loose sheets in 75 hours.
