Question

A clerk can sort 375 sheets per hour. If there are 225 sheets in an inch, how long will it take her to file 125 inches of loose sheets?

Answer 1

`75` hours.

Explanation:

There are `225` sheets in an inch,

hence each sheet is `1/225` inch thick

and as clerk sorts `375` sheets per hour,

this means `1/225xx375=5/3` inches of sheets can be sorted in one hour

Hence `125` inches of sheets can be sorted in

`125-:5/3=125xx3/5=25xx3=75` hours.
