Final answer:
The fastest lap time was for Lap C, with a time of 37.83 seconds.
Step-by-step explanation:
The student asked for the fastest time it took the race car driver to complete one lap out of the three given times: Lap A, Lap B, and Lap C. To answer this, we simply identify the smallest number among the three lap times, as the smallest time indicates the fastest lap.
Here are the recorded lap times:
- Lap A: 39.28 seconds
- Lap B: 38.9 seconds
- Lap C: 37.83 seconds
Upon comparison, we can see that Lap C is the fastest lap with a completion time of 37.83 seconds.
