Question

an athlete is running on a circular track . He runs a distance of400m in 25 s before returning to his original position. what is his average speed???

Answer 1

Hey
Average speed =Total distance /Total time taken
=> 400/25
=> 16 m/s
I hope this helps. :)

Answer 2

Answer:

Given: Total distance travelled = 400 m

Total displacement = 0, as he returns to his original position.

Total time = 25 seconds.

Average speed = ?, Average velocity = ?

Average speed = Total distance covered / Total time taken

=> Average speed = 400 / 25

=> 16 m/s

Average velocity = Total displacement / Total time taken

=> 0 / 25

=> 0 m/s
