Is the equation 344+0.6x(t-20)? I'm not getting this at all?
How long does it take for sound to arrive at the back of a big auditorium if the temperature is 33 oC and the stage is 29 m away? answer in seconds

The Eq I have is:
V = 331.4 + 0.6T.
T = Temp. in deg celsius.
V = Velocity in m/s.

V = 331.4 + 0.6*33,
V = 331.4 + 19.8 = 351.2m/s.

t = d/V = 29m / 351.2m/s = 0.08257s.
