A. (15,1/2)
B. (2,60)
C.(1 1/2,30)
D. (1,30)

Answer 1

The constant of proportionality represents the ratio between the number of pages read and the time it takes to read them. In this case, Ruth can read 15 pages in 30 minutes, so the ratio would be:

15 pages / 30 minutes = 1/2 page per minute

Therefore, the correct answer is: A. (15, 1/2)
