Question

what is average speed?
○ how fast velocity changes
○ total distance divided by total time
○ the speed at any moment or instant in time
○ all of the above
○ none of the above

Explanation:

• "How fast velocity changes" describes acceleration, not average speed.
• "Total distance divided by total time" is the correct formula for average speed.
• "The speed at any moment or instant in time" is instantaneous speed, not average speed.
• Since only the second option is correct, "all of the above" is wrong, and "none of the above" is also wrong.

Answer:

B. total distance divided by total time (assuming the options are labeled as A, B, C, D, E with A: how fast velocity changes, B: total distance divided by total time, C: the speed at any moment or instant in time, D: all of the above, E: none of the above)
