If i read 52 pages in 2 hrs and tim reads 1/4 more in 2 and1/2 hr. who read faster?

They read at the same speed
If we split the time where you read into half hour intervals we would have
13 pages per 30 minutes
and since * 52= 13 and the time added is 30 minutes we know that You and Tim read at the same speed. 

So Tim read 13 pages =1/4 of 52 pages in (2 and 1/2 hr) - (2hrs) = 1/2 hr
So Tim will read 26 pages in 1 hr and  that means Tim read 52 pages in 2 hrs, the same with You! The answer its that bouth read in the same time.

The correct answer will be d. -4
