Answer:
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

- Speed, being a scalar quantity, is the rate at which an object covers distance.
- The average speed is the distance (a scalar quantity) per time ratio.
- On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
- Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
- For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.
