if jack was traveling north 120 miles and it took him 3 hours to get there. what is the velocity that jack was traveling? is this a scalar or vector

Velocity of an object is given as
[tex]velocity = \frac{displacement}{time}[/tex]
now we have
[tex]displacement = 120 miles[/tex]
time = 3 hours
now from above formula
[tex]v = \frac{120}{3}[/tex]
[tex]v = 40 miles/hour[/tex]
so its velocity is 40 mph and its a vector quantity whose direction is towards NORTH
correct answer is B
