Question

What is the speed of sound at the atmospheric temperature of 30°c?

Answer 1

We know the equation for calculation of speed of sound at temperature:
v = 331 m/s + (0.6 m/s/C) * T
Here, T = 30 C
v = 331 m/s + (0.6 m/s/C) * 30 C
v = 331 m/s + 18 m/s
v = 349 m/s

In short, Your Answer would be 349 m/s

Hope this helps!
