The arithmetic average of speeds over a given time period is a pretty much useless measure - of anything!
If both speeds are used for the same amount of time, the average speed is just the sum of the two speeds divided by 2. If one speed is used for a longer time than another, you will have to calculate the total distance traveled for each speed (speed x time), and then divide by the total time (add the times).
It is given as an average because the distance varies over time.
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
To find the average speed of an object over a given time, you divide the total distance traveled by the object by the total time taken to cover that distance. Mathematically, average speed = total distance / total time.

Average over time refers to the calculation of the mean or average value of a given variable over a specific period. This involves adding up all the values of the variable during that period and dividing by the number of observations. It helps in understanding the trend or behavior of the variable over time.
Average speed is a representation of all your speeds between two points, constant speed is just unchanging speed.
To find the average velocity when there are two different speeds, you can use the formula: average velocity = total distance traveled / total time taken. Simply calculate the total distance traveled and total time taken for the two different speeds, and plug these values into the formula to find the average velocity.
Depends on how long each of the speeds has been maintained - over the same distance, the same time, or neither.

The average speed of a car is how fast it averages over a span of time. Instantaneous speed is how fast the car is moving at any given time which is measured using a real-time speedometer.
Average speed is a value of all the speeds you have travelled at over a certain length of time. Top speed is the absolute highest or fastest speed that you have ever reached. (A one time speed value).
