The constant of proportionality can be found by looking at any pair of values (time, pages read) from the table.
For example, we can choose the pair (1, 30).
To find the ratio of the constant of proportionality, we divide the number of pages read by the time:
constant of proportionality = pages read / time = 30 / 1 = 30.
Therefore, the ratio of the constant of proportionality is:
(1, 30)
Use the table to answer the question.
Time (hours) Pages read
12 15
1 30
112 45
2 60
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?
