Answer:

Option C is the correct answer.

Explanation:

The speed of sound in air is given approximately by  

[tex]v=331.4+0.6T_c[/tex]

Here [tex]T_c[/tex] is the temperature in degree Celsius.

Temperature [tex]T_c=30^0C[/tex]

Substituting we will get

     v = 331.4 + 0.6 x 30 = 349.4 m/s

Option C is the correct answer.

Answer:

349.4 m/s
