The wind speed near the center of a tornado is represented by the equation S=93logd+65, where d is the distance, in miles, that the tornado travels and S is the wind speed, in miles per hour. If the wind speed was 130 miles per hour, which equation could be used to find the distance that the tornado traveled?

Respuesta :

Answer:

Step-by-step explanation:

Given

Tornado speed is given by

[tex]S=93\log_{10} d+65[/tex]

where, S=wind Speed

d=distance in miles

if [tex]S=130 mph[/tex]

then

[tex]130=93\log_{10} d+65[/tex]

[tex]93\log_{10} d=65[/tex]

[tex]\log_{10} d=0.6989[/tex]

[tex]d=10^{0.699}[/tex]

[tex]d=5.0003\ miles [/tex]
