Chloe is playing the flute some distance away from a crowd. If the atmospheric temperature is 15°C, what is the speed of the sound traveling from the flute?

Question

A.
340 meters/second
B.
330 meters/second
C.
320 meters/second
D.
310 meters/second
E.
300 meters/second

Answer 1

The speed of sound in air can be approximated by the formula:

\[ v = 331.3 + (0.6 \times T) \]

where \(v\) is the speed of sound in meters per second and \(T\) is the temperature in degrees Celsius.

In this case, at 15°C, we can calculate the speed of sound as follows:

\[ v = 331.3 + (0.6 \times 15) = 331.3 + 9 = 340.3 \text{ meters/second} \]

Given the options, the closest answer is:

A. 340 meters/second.
