Introduction:
When comparing the speeds of two objects, it is important to consider the concept of relative motion. The speed of an object can be determined by comparing its displacement over a certain time period. By comparing the displacements of two objects over the same time interval, we can determine which object is moving faster.

Determining Speed:
To determine the speed of an object, we need to measure its displacement and the time taken. The formula for speed is:

Speed = Displacement / Time

The displacement is the change in position of the object, while the time is the duration of the motion. By using this formula, we can calculate the speed of each object separately.

Comparing Speeds:
To compare the speeds of two objects, we need to consider their individual speed values. The object with the higher speed will be considered to be moving faster than the other.

Example:
Let's consider two cars, Car A and Car B, traveling along a straight road. Car A covers a distance of 100 meters in 10 seconds, while Car B covers a distance of 150 meters in the same 10 seconds.

- Car A's speed = 100 meters / 10 seconds = 10 meters per second
- Car B's speed = 150 meters / 10 seconds = 15 meters per second

In this example, Car B has a higher speed than Car A, so we can conclude that Car B is moving faster.

Conclusion:
To determine which object is moving faster, we need to calculate the speeds of each object and compare them. The object with the higher speed will be considered to be moving faster than the other. Remember to consider both displacement and time when calculating speed.

The thing which allows us to decide whether an object is moving faster than other is their speed and time taken to cover equal amt of distance in given time.
