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.
The neritic zone is permanently covered with generally well-oxygenated water, receives plenty of sunlight and has low water pressure; moreover, it has relatively stable temperature, pressure, light and salinity levels, making it suitable for photosynthetic life.
The correct answer is intensity.
The intensity signifies towards the extent of energy exhausted at the time of performing exercise. The intensity differs with each individual. It has been observed that intensity possess an influence on what fuel the body utilizes and what kind of changes the body makes after performing exercise.
