Answer 2

Answer: The speed of Oliver is
`24(1)/(3)` pages per hour.

Step-by-step explanation: Given that Oliver reads
`28(1)/(2)` pages of a book in
`1(1)/(6)` hours.

We are to express his speed in pages per hour.

We will be using the UNITARY method to solve the given problem.

Number of pages read by Oliver in
`1(1)/(6)=(7)/(6)` hours is

`=28(1)/(2)=(57)/(2).`

Therefore, the number of pages read by Oliver in 1 hour is given by

`(57)/(2)*(6)/(7)=24(3)/(7).`

Thus, the speed of Oliver is
`24(1)/(3)` pages per hour.
