Calculating VelocityIn order to calculate velocity you need to find the distance an object has traveled and in what time interval. Since we are calculating the velocity between two points we will calculating the average velocity.

The BattleBot Nightmare travels a distance of 12 meters, in a time of 0 to 8 seconds. What is the average velocity of Nightmare between this time interval?
