Lamont read 313.5 pages of his book in 5 hours 30 minutes. if he reads at a constant rate, hiw many pages of his book did lamont read in 1 hour?

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

57 pages per hour I think

Hope i can you!
