12 2
34 3
1 4
It takes Julian 1/2 hour to walk 2 miles. He decides to start walking in his spare time, but because he wants to make sure he has enough time to go a desired distance he created the data table. At which ratio does the constant of proportionality appear?

To find the constant of proportionality in the context of the given data, you need to look for a ratio that represents the relationship between hours walked and miles walked.

From the data in the table, we can extract the quantities:

  1. (14 hours, 1 mile)
  2. (12 hours, 2 miles)
  3. (34 hours, 3 miles)
  4. (1 hour, 4 miles)

To calculate the constant of proportionality, we can find the ratio of miles walked to hours spent walking. This can be computed as follows:

  • For 14 hours and 1 mile: \( \frac{1}{14} \) miles per hour.
  • For 12 hours and 2 miles: \( \frac{2}{12} = \frac{1}{6} \) miles per hour.
  • For 34 hours and 3 miles: \( \frac{3}{34} \) miles per hour.
  • For 1 hour and 4 miles: \( \frac{4}{1} = 4 \) miles per hour.

From this analysis, the constant of proportionality appears to be indicated by the last ratio calculation involving (1 hour, 4 miles), where the result is 4 miles per hour.

Therefore, the answer to your question regarding the ratio that represents the constant of proportionality is:
