    False. The average speed, by definition, is Vavg = S/T = 2piR/T; where S = 2piR is the distance traveled once around the track in T time. R is the radius of the circular track. And S is the circumference.

    As you can plainly see 2piR > 0; so Vavg > 0 must be true. Therefore Vavg = 0 is false. QED.

    Now having answered your question. I have one for you. What's the average velocity in this case? Hint: It's not the same as the average speed.

  • I do not think so because speed = distance traveled / time

    A distance cannot be zero if traveled in any direction.So as going in a track distance have a certain value and it is not reduced in relative to the direction So average speed cannot be zero.

    please search more and be logical before accepting the answer.
