Answer:
This question is incomplete
Explanation:
This question is incomplete because the time taken by each individual was not provided but a guide can be used to determine the most appropriate unit to represent the winning time. The most appropriate unit will be determined in the manner below.
If the times are equivalent and the time taken (to finish 30 hot dogs) across all contestants are less than 60 secs, the most appropriate unit will be seconds. But if the time taken across all contestants are more than 60 secs (or 1 minute) but less than 3600 secs (or 60 minutes), the most appropriate unit will be minutes. However, if the time taken across all contestants are more than 3600 secs (or 60 minutes or 1 hour), the most appropriate unit will be hours.
