Ruth can read 15 pages in 30 minutes. She decides to create a table to keep track of her progress. From the data provided, at what ratio is the constant of proportionality?
1. (15, 1/2)
2. (1, 30)
3. (2, 60)
4. (1 1/2, 30)
To find the ratio of the constant of proportionality, we need to determine how the number of pages read relates to the amount of time it takes.
Given that Ruth can read 15 pages in 30 minutes, we can set up the ratio as 15 pages to 30 minutes:
15/30 = 1/2
Therefore, the ratio of the constant of proportionality is (15, 1/2) or option 1.
To determine the ratio of the constant of proportionality, we need to analyze the relationship between the number of pages read and the amount of time taken.
From the given information, we know that Ruth can read 15 pages in 30 minutes. This means there is a constant ratio between the number of pages read and the time taken.
To find the ratio, we can divide the number of pages read by the time taken. In this case, it would be 15 pages / 30 minutes, which simplifies to 1/2.
Therefore, the correct answer is option 1: (15, 1/2).
To find the ratio of the constant of proportionality, we can divide the number of pages read by the time taken. From the given information, Ruth can read 15 pages in 30 minutes.
The ratio can be calculated as follows:
Ratio = Number of pages / Time taken
Ratio = 15 pages / 30 minutes
Ratio = 1/2
Therefore, the correct answer is option 1. (15, 1/2). The ratio of the constant of proportionality is 1/2.
