Given that the wind speed near the center of a tornado is
[tex]\begin{gathered} S=93\log d+65 \\ \text{where,} \\ d=\text{distance in miles} \\ S=\text{ wind sp}eed\text{ in miles per hour} \end{gathered}[/tex]Given that the tornado traveled 51 miles, that is d = 51 miles, its wind speed in miles per hour will be:
[tex]\begin{gathered} S=93\log 51+65 \\ S=158.8+65 \\ S=223.8 \end{gathered}[/tex]Therefore, the wind speed of the tornado if it traveled 51 miles is 223.8 miles per hour (to the nearest tenth)
