Velocity is a measure of speed, in distance over time. The route or distance travelled is independent because it bears no relevance. For instance, if one person drove 50 miles at 50 miles per hour the trip would take one hour. If another drove 100 miles at 50 miles per hour the trip would take two hours. In these two instances the routes are different, the times the trip takes are different but the velocity ( 50 mph ) is the same.

What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
If a car travels 6 inches on an Airtrack in .195 seconds what is its average velocity?
Well, isn't that just a happy little question! To find the average velocity, we simply divide the distance traveled by the time taken. In this case, the car traveled 6 inches in 0.195 seconds, so the average velocity would be 6 inches / 0.195 seconds = 30.77 inches per second. Just imagine that car gliding along the Airtrack, creating a beautiful and steady pace.
How does average speed relate the distance covered and the time taken for travel?
Average speed = Distance covered/Time taken
Why is acceleration measured in meters seconds squared?
Acceleration is the rate of change in velocity, that is the finishing velocity minus the starting velocity divided by the time taken for that change. Velocity is the rate of change in distance, that is the finishing distance minus the starting distance divided by the time taken for that change. Distance may be measured in metres and time in seconds. In that case velocity would be measured in metres per second. Acceleration is then measured in (metres per second) per second or metres per second2.
