To determine if the quantities in the data table represent a proportional relationship, we need to compare the ratios of miles traveled to hours biked for each entry in the table.
Calculating the ratios:
- For 1 hour: \( \frac{12 \text{ miles}}{1 \text{ hour}} = 12 \)
- For 2 hours: \( \frac{26 \text{ miles}}{2 \text{ hours}} = 13 \)
- For 3 hours: \( \frac{30 \text{ miles}}{3 \text{ hours}} = 10 \)
- For 4 hours: \( \frac{48 \text{ miles}}{4 \text{ hours}} = 12 \)
Now, let's summarize the ratios:
- 1 hour: 12
- 2 hours: 13
- 3 hours: 10
- 4 hours: 12
Since the ratios are not constant (they vary for each time period), the quantities do not have a proportional relationship.
Therefore, the correct response is: 3. No, not all of the ratios are proportional or have equivalence.
