It takes Julian 12 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 from the provided data, we can analyze the relationship between the hours walked and the miles walked.

From the table, we have the following pairs:

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

Let's calculate the ratio of miles to hours for each pair:

  1. For (14 hours, 1 mile): \[ \text{Ratio} = \frac{1 \text{ mile}}{14 \text{ hours}} = \frac{1}{14} \]

  2. For (12 hours, 2 miles): \[ \text{Ratio} = \frac{2 \text{ miles}}{12 \text{ hours}} = \frac{1}{6} \]

  3. For (34 hours, 3 miles): \[ \text{Ratio} = \frac{3 \text{ miles}}{34 \text{ hours}} \approx \frac{1}{11.33} \]

  4. For (1 hour, 4 miles): \[ \text{Ratio} = \frac{4 \text{ miles}}{1 \text{ hour}} = 4 \]

The ratios of miles to hours do not show a constant value; thus it is not directly proportional in the traditional sense. However, we can still identify the constant of proportionality in the table from the pairs:

The pairs contain values:

  • (14, 1) where 1 mile corresponds to 14 hours
  • (12, 2) where 2 miles corresponds to 12 hours
  • (34, 3) where 3 miles corresponds to 34 hours
  • (1, 4) where 4 miles corresponds to 1 hour

Among the responses provided, the ratio that can be identified as a form of the constant of proportionality is:

  • (14, 1) represents the relationship in hours and miles.

Thus, the answer is:

(14, 1).
