time (hours): 1/2 1 1 1/2 2

Question

Pages read: 15 30 45 60

ruth can read 15 pages in 30 minutes she decides to create s table to keep track of her progress from the data provided at what radio is the constant proportionality

Answer 1

To find the constant proportionality, we can create a table of the time (hours) and the corresponding number of pages read:

Time (hours): 1/2 1 1 1/2 2
Pages read: 15 30 45 60

The constant proportionality can be found by dividing the number of pages read by the time taken for each interval:

For the first interval, from 1/2 hour to 1 hour, the number of pages read increases by 30 (from 15 to 30), while the time increases by 1/2 hour.

So, the constant proportionality for this interval is 30/0.5 = 60 pages per hour.

For the second interval, from 1 hour to 1 1/2 hours, the number of pages read increases by 15 (from 30 to 45), while the time increases by 1/2 hour.

So, the constant proportionality for this interval is 15/0.5 = 30 pages per hour.

For the third interval, from 1 1/2 hours to 2 hours, the number of pages read increases by 15 (from 45 to 60), while the time increases by 1/2 hour.

So, the constant proportionality for this interval is 15/0.5 = 30 pages per hour.

From the data provided, we can see that the constant proportionality is 30 pages per hour.
