Ans=2hr.40 min.
For Ist case->Readable part of page=90%,so Actual pages read in 1 hr=0.9*100=90
For IInd case->Readable part of page=80%,so pages to be read=0.8*300=240
For 90 pages it took 1 hr,so for 240,time taken=240*1/90=8/3=2 2/3hr.

(*It is assumed that speed of another girl is same as the first girl and
each inch of pages contains same no. of lines in both the cases)
