Distance is a scalar. The straight line distance that an object moves from the starting position to the final position and what direction the object moved . Displacement is measured in meters. Displacement is a vector. The distance that an object travels divided by the time need for the trip.
Speed is a scalar.
The displacement of an object divided by time . This means that whatever the direction of the displacement the velocity will have the same direction. The rate at which velocity changes is called acceleration. Acceleration is calculated as velocity divided by time . Acceleration is a vector.
