Well, the aswer is 3 1/5.
You can analize it looking at the fact that she reads 3/5 pages/1 minute(three fifths per minute) and that she she will read for 16/3 min(5 1/3). So you multiply the number of pages for the cuantity minutes(3/5*16/3). That way you will get to 48/15, which simplified is 16/5, and if you convert it to a whole fraction youll get 3 1/5.
Good luck.
