Final answer:
The relationship between time spent swimming and the number of weeks is not necessarily proportional.
Step-by-step explanation:
No, the relationship between the time spent swimming and the number of weeks is not necessarily proportional. To determine if the relationship is proportional, we would need to analyze the given data and see if there is a consistent ratio between the two variables. However, since we do not have any information about the number of weeks spent swimming, we cannot make a conclusion about proportionality.
