Ann walked 1.5 miles south to her house in 0.5 hours. what is Ann's speed? what is Ann's velocity

$v= \frac{d}{t}$

Here, d is distance and t is time and v if we take it with direction then it is called velocity and if we take it without the direction then it is called speed.

Given $d=1.5 miles$ and $t=0.5 hours$ .
