Before solving this problem first we have to understand the basic of velocity and speed.The speed is a scalar quantity which means the rate of change of distance covered by a particle .As the distance traveled is a scalar quantity as it has no specific directions,so is the speed.It has simply magnitude.
then we have to understand the velocity.Velocity is a vector quantity.IT is defined as the rate of change displacement of the particle or we may say the speed in a given direction .As we know that displacement is the minimum distance traveled by a particle which is nothing else except the straight line joining two points,so it has direction.hence velocity has a magnitude as well as direction.one has remember that the magnitude velocity is always smaller than or equal to the speed
so the answer will be DIRECTION i.e velocity indicates the direction of motion .
