answer
-28 K
explanation
we have the equation V = 331 +0.6T as the speed of sound changes with temperature
rearrange to solve for T
V = 331 +0.6T
V - 331 = 0.6T
T = [tex]\frac{V-331}{0.6}[/tex]
plug in 314.2 for V
T = [tex]\frac{314.2-331}{0.6}[/tex]
T = -28
K
note that temperatures under 0K are impossible to reach, but the value is -28 K by the equation
