No, I apologize for the mistake. Let me calculate the ratio of the constant of proportionality using the data provided.

The increase in pages read from 15 pages to 30 pages is 15 pages.
The increase in time from 1/2 hour to 1 hour is 1/2 hour.

To find the ratio of the constant of proportionality, we divide the increase in pages read by the increase in time:
15 pages / (1 - 1/2) hour = 15 pages / 1/2 hour = 30 pages/hour

Therefore, the ratio of the constant of proportionality is 30. This means that Ruth reads 30 pages per hour.
