Answer:
38.77 seconds
Step-by-step explanation:
Given that,
Kim finished a race in 48.47 seconds.
This is 9.7 seconds faster than her practice time.
We need to find Kim's practice time.
Finished time = 9.7 + (practice time)
i.e.
Practice time = (Finished time-9.7)
= 48.47 - 9.7
= 38.77 seconds
Hence, the practice time is 38.77 seconds.
