Final answer:
The total time spent by all competitors performing in a 2-hour gymnastic meet with 8 competitors is 2 hours.
Step-by-step explanation:
- Convert 2 hours to minutes: 2 hours x 60 minutes/hour = 120 minutes.
- Calculate the total time spent by all competitors performing: 8 competitors x 15 minutes/competitor = 120 minutes.
- Convert 120 minutes to hours: 120 minutes / 60 minutes/hour = 2 hours.
Therefore, the total time spent by all competitors performing is 2 hours.
