Lets find out how many pages he can read in a minute:
313.5 pages in (60*5)+30 = x minutes, x = 330 minutes
313.5/330 = .95 pages a minute
1 hour is 60 minutes
.95 * 60 = 57 pages in an hour.
Edit:
cross multiply to find how many pages read in an hour
313.5 pages x pages
-------- = -----------------
5 hours 30 mins (330 mins) 60 mins
(313.5*60)/330 = 57
313.5 pages in (60*5)+30 = x minutes, x = 330 minutes
313.5/330 = .95 pages a minute
1 hour is 60 minutes
.95 * 60 = 57 pages in an hour.
