To find the ratio of the constant of proportionality, we need to determine the relationship between time and pages read. Looking at the table, we can see that as time increases, the pages read also increase. Therefore, the constant of proportionality is the ratio of "Pages Read" to "Time(Hours)".
From the data provided, the ratio of the constant of proportionality is (Pages Read / Time(Hours)):
For the first row: 15 / (1/2) = 30
For the second row: 30 / 1 = 30
For the third row: 45 / (3/2) = 30
For the fourth row: 60 / 2 = 30
Therefore, the ratio of the constant of proportionality is 30.
The correct option is B (1, 30).
Use the table to answer the question.
Time(Hours) / Pages Read
T:1/2 PR:15
T:1 PR:30
T:1 1/2 PR:45
T:2 PR:60
