Solution Steps
Step 1: Identify the Proportional Relationship
The table shows a proportional relationship between minutes and pieces of cabbage eaten. The relationship can be expressed as:
\[
\text{Pieces of cabbage} = k \cdot \text{Minutes}
\]
where \( k \) is the constant of proportionality.
Step 2: Calculate the Constant of Proportionality
To find \( k \), we can use any row from the table. Let's use the first row:
\[
3 = k \cdot 15
\]
Solving for \( k \):
\[
k = \frac{3}{15} = 0.2
\]
Step 3: Verify the Constant of Proportionality
We can verify \( k \) using another row from the table. Let's use the second row:
\[
5 = k \cdot 25
\]
Solving for \( k \):
\[
k = \frac{5}{25} = 0.2
\]
The constant of proportionality is consistent across the table.
Final Answer
The constant of proportionality is \(\boxed{0.2}\).
