According to Laplace correction of speed of sound ,
Speed of sound is directly proportional to square root of [ temperature / molecular mass]
According to this law : speed of nitrogen / speed of oxygen = 1
speed of nitrogen = square root of [ 288/28]
speed of oxygen = square root of [ T/32]
solving these 3 equation T = 329 K OR in degree celsius = 56
