Final answer:
The correct equation for calculating speed is Speed = Distance/Time. By dividing the distance traveled by the time taken, you get the speed, which is a scalar quantity indicating how fast an object is moving without regard to its direction.
Step-by-step explanation:
The correct relation is Speed = Distance/Time. This equation means that to find the speed of an object, you divide the distance it traveled by the time it took to travel that distance. To apply this, if you are given a distance in meters and a time in seconds, you can calculate the speed in meters per second (m/s). For example, if a car traveled 100 meters in 5 seconds, its speed would be 100 meters divided by 5 seconds, resulting in a speed of 20 m/s.
It's important to remember that speed is a scalar quantity, which means it only has magnitude and no direction. This is different from velocity, which is a vector quantity that includes both magnitude and direction.
