How is average speed calculated?

Average speed is calculated by dividing the total distance traveled by the total time taken for the journey. This formula provides a straightforward way to determine how fast an object is moving over a specific period, allowing for a clear understanding of the motion involved.

In practical terms, if a vehicle travels 150 kilometers in 3 hours, the average speed would be calculated as 150 km divided by 3 hours, resulting in an average speed of 50 kilometers per hour. This formula is foundational in physics for analyzing motion and offers insight into how distance and time relate to speed.

The other choices do not accurately represent the standard calculation for average speed, reinforcing the validity of the correct answer.
