Answer:

[tex]V_R=5.80mph(-\hat j )[/tex]

Explanation:

From the question we are told that

Speed of man [tex]V_m=3.30mph[/tex]

Speed of wind  [tex]V_w=-2.70mph[/tex]

Generally the Relative wind speed V_R is mathematically given directly as

   [tex]V_R=V_w-V_m[/tex]

   [tex]V_R=-2.7-3.30[/tex]

   [tex]V_R=-5.80mph[/tex]

Therefore the relative wind speed will the person sense

   [tex]V_R=5.80mph(-\hat j )[/tex]
