Question

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

Answer 1

The correct answer is B. (15. 1/2).

To find the constant of proportionality, we need to find the ratio between the number of pages read and the time taken to read them.

From the table, we can see that when Ruth reads 15 pages, she takes 30 minutes.

So the ratio between the number of pages read and the time taken is 15:30, which simplifies to 1:2.

Therefore, the constant of proportionality is 1/2.
