Expert Answer:

Figure shows the travelled distances and directions as given in question . Initial starting point is A and final destination is D .
 
Average velocity = Net displacement / time
 
Net displacemet = AD = begin mathsize 14px style square root of 14 squared plus space 13 squared end root space equals space 19.1 space k m end style
Average velocity = 19.1 km / 0.5 hr = 38.2 km/hr
 
Directon of velocity as shown in figure is 47o south of west
