velocity of sound  v is proportional to  the square root of the absolute temperature T of the ideal gas through which it travels.  This is valid for ideal gases or air.

       v  α  √T
   v2 / v1 = √(T2 / T1)

   v1 = 339 m/sec  T1 = 273.15 + 15 = 288.15 °K
   v2 = ?      T2 = 273.15 + 115 = 388.15 °K
         v2 = 339 m/s * √(388.15 / 288.15) =  393.45 meters/sec
