Distance traveled (dashed line) is a measure of length along the actual path.
Displacement (blue line) is how far the object is from its starting point, regardless of how it got there.
Speed: time rate of change of distance; how far an object travels in a given time interval
Velocity includes directional information: time rate of change of displacement
The instantaneous speed is the speed as given on your speedometer. The speed at that instant.(Speed given by the speedometer)
The average speed is the total distance traveled by an object divided by the total time taken to travel that distance.
