Question

4. An athelete is running on a circular track. He runs a distance of 400 m in 25 s

before running on his original position. What is his average speed & velocity?​

Answer 1

Explanation:

Distance= 400m

time = 25sec

avg. speed = total distance/ time

= 400/25 = 16m/s

Now, avg velocity= displacement/ time

here, displacement= 0 (because he comes back to original position)

=> avg velocity= 0/25 = 0m/s
