Is final velocity a vector or scalar?

A ball starts from rest at point A and rolls .9 meters east to point B with an average velocity of 2 m/s. What was the velocity of the ball at B?
Given:
Vi=0 m/s 
d (displacement)= .9m east
average velocity= 2 m/s 
Vf= ???
 
average velocity = Vf + Vi divided by 2
 
is the answer 4 m/s or 4 m/s East? 
Does the answer for final velocity include direction or no?
