1. The problem statement, all variables and given/known data The distance between a loudspeaker and the left ear of a listener is 1.90 m. (a) Calculate the time required for sound to travel this distance if the air temperature is 20°C. 2. Relevant equations I am not sure, I tried looking in my text...but the only equation I could come up with is velocity = sqroot(ykT/m) where y = specific heat, k is the Boltzmann constant, T is the given temp in K, and m is the distance.. 3. The attempt at a solution I have no idea where to even start, because only 2 things are known x in meters and the Temp 20 deg or 293 K. Can anyone help me out?
