Mean Speed is also known as average Speed …

Mean Speed is also known as average Speed. Mean Speed or Average speed is the total distance traveled divided by the total time taken to cover that distance. It is a measure of how fast an object is moving on average over a given period of time.
The formula for average speed is:
Average speed = total distance / total time
For example, if a car travels 100 miles in 2 hours, the average speed of the car would be:
Average speed = 100 miles / 2 hours
Average speed = 50 miles per hour
So, the car traveled at an average speed of 50 miles per hour over the 2-hour period.
