Answer: 75hours
Explanation:
If there are 225 sheets in one inch that means that in 125 there will be 28,125 sheets because you will have to multiply. And if you can sort 375 pero hour that will mean than in 75 hours you will sork all sheets because 28,125 divided by 375 sheets pero hour will give 75 hours.
125 inch * 225 sheet/ inch= 28,225 sheets
28,225 sheets divided by 375 sheets/hour=75 hours
