Answer 1

Explanation:

Given data

distance covered = 28m

time taken = 40 sec

As, the question she completed 1 round that means she again came to the starting point. so,

displacement covered = 0m

Average speed = distance/time

= 28/40 = 0.7m/s

Average velocity = displacement/time

= 0/40 = 0m/s
