Test On Monday...please help!
My home is exactly 7.8 km from the Stadium where the 4th of July fireworks are held. The time difference between when I see a flash and when I hear the corresponding sound is 22.4073542085608 s. What is the temperature (in degrees Celsius) of the air?
Vsound = sqrt (GAMMA * R * T) / M
T = 20 degrees Celsius + 273 = 293
V = 7800/22.4073542085608 = 348.1 m/s
T = Vsound^2 * M / GAMMA * R
But I don't know M, GAMMA, or R?

The Attempt at a Solution
T = 20 degrees Celsius + 273 = 293
V = 7800/22.4073542085608 = 348.1 m/s
T = Vsound^2 * M / GAMMA * R
