Answer:

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"#.
