The speed at any instant is called
instantaneous speed
average speed
unknown speed
Average speed is
the distance of the whole trip divided by the total time of the trip.
The speed at any moment in time
The speed that is marked on the limit speed sign
Velocity is
directed speed
the same as speed
how fast something moves without considering direction
acceleration is...
change in speed divided by distance traveled
