The velocity of the sound will be 329 meters per second at -2.3975 degree Celsius.

$v=20 √(273+t) \\ \\ 329=20 √(273+t) \\ \\ 16.45 =√(273+t) \\ \\ 270.6025=273+t \\ \\ t=-2.3975$

This solution can also be seen from graph attached below. The blue horizontal line shows the velocity equal to 329 meter per second.

The velocity of sound in air is given by the equation please only answer if you're-example-1
