* Average speed is calculated over a period of time. It takes into account the total distance traveled divided by the total time taken.
* Speed can vary throughout the journey. An object might start slow, speed up, slow down, or even stop during its journey.
Example: Imagine a car traveling:
* 0-30 minutes: The car travels at a constant 30 mph.
* 30-60 minutes: The car speeds up to 60 mph.
The car's average speed over the hour would be somewhere between 30 mph and 60 mph, depending on how long it spent at each speed. However, during the second half of the journey, the car was moving *faster* than its average speed.
Key takeaway: Average speed is a measure of the overall journey, not necessarily the speed at any given moment.
