Answer 1

velocity indicates magnitude as well as direction.

a car is travelling with a velocity 90km/hr. it tells that the car is moving with a speed of 90 km/ hr in a paritcular direction. thus velocity is a vector quantity..

Answer 2

Velocity is a vector quantity
----------------------------------------------
velocity is defined as rate of change of displacement

as we know that displacement is a vector quantity and time is scalar and vector by scalar gives a vector hence Velocity is a vector quantity as it wil have both magnitude and direction
