Answer:
714 pages total in 42 hours of reading
Step-by-step explanation:
First, Determine how many pages Madelyn can read per hour, the "unit rate."
That would be
425 pages
---------------- = 17 pages per hour
25 hours
Then the number of pages she will have read in 42 hours is
(unit rate)(number of hours), or
(17 pages/hr)(42 hrs) = 714 pages total in 42 hours of reading
