Final answer:
The student determined that the speed of sound is approximately 171.65 m/s.
Step-by-step explanation:
To calculate the speed of sound, we can use the formula:
Speed of sound = Distance / Time
From the question, we are given:
Distance = 109 m
Time = 0.635 s
Substituting these values into the formula, we have:
Speed of sound = 109 m / 0.635 s = 171.65 m/s
Hence, the student accurately calculates the speed of sound as approximately 171.65 meters per second, showcasing the application of the speed formula utilizing the provided distance and time values to derive this measurement.
