AVERAGE SPEED |
|
Definition
* The distance travelled in a specific time
* The needle of the speedometer moves up & down during a typical trip, because it is showing the instantaneous speed-the speed of the vehicle at a particular instant. Because the speed during a typical trip varies, the average speed for the trip is more meaningful than various instantaneous speeds |
