Ann's speed is "3 mi/h". Her velocity is "3 mi/h south.

Explanation:

v=(Deltad)/(Deltat), where v is velocity, Delta d is displacement, and Deltat is time interval.

Substitute the known values into the equation.

v=(1.5"mi")/(0.5"h")="3 mi/h" (without direction, this is her speed)

The direction given was south, so Ann's velocity is "3 mi/h south".
