If she reads 90 pages in 2.5 hours, then she reads
90%2F2.5pages in an hour.
=36pages in an hour.
At the same rate,
She reads 36 pages in 1hr
She will read 225 pages in xhrs
(I really wish I could simplify this, but since there's no visual, I hope you understand)
She will read 225 pages in %28225%2A1%29%2F36hrs
She will read 225 pages in 6.25hrs.
