Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :

Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, 

But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, 
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.

Induced movement or induced motion is an illusion in which people tend look into it moving even it is really not moving.
