Question

what is instantaneous 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
previous

Explanation:

• "how fast velocity changes" describes acceleration, not instantaneous speed.
• "total distance divided by total time" is the formula for average speed.
• "the speed at any moment or instant in time" accurately defines instantaneous speed.
• Since only one option is correct, "all of the above" is wrong. And as one option is correct, "none of the above" is also wrong.

Answer:

C. the speed at any moment or instant in time
