anonymous · Answer

just divide the number of pages read by how many hours

so preston read 28/2=14 pages per hour

and bethany read 85/5=17 pages per hour

calculusxy · Answer

The answer is D. 

pages divided by the hour

28/2=14 (Preston)
85/5=17 (Bethany)

17 (Bethany)- 14(Preston)= 3 pages slower per hour.
