The speed of the wind $3v$ is 30 mph. The wind $3v$ is 3 times faster than $v$ and it is blowing in the same direction as $v$.
$v = 6~i+8~j$ $3v = 18~i+24~j$ The speed of the wind is the magnitude of the vector $3v$. We can find the magnitude of the vector $3v$: $\vert 3v \vert = \sqrt{18^2+24^2}$ $\vert 3v \vert = 30$ The speed of the wind $3v$ is 30 mph. The wind $3v$ is 3 times faster than $v$ and it is blowing in the same direction as $v$.
