The speed of sound is given by:

$v=331\sqrt[]{1+(T)/(273)}$

then in this case the speed is:

$v=331\sqrt[]{1+(31)/(273)}=349.29$

The distance is given by:

plugging the values given we have:

$\begin{gathered} d=(349.29)(7) \\ d=2445.03 \end{gathered}$

Therefore the storm is 2445.03 meters away
