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.
In plants carbon dioxide is reduced into simple carbohydrates (e.g. glucose) with energy absorbed from the sun within the chloroplast.
This is also known as photosynthesis.
Hope this helps!
Plants use the sun to produce food then animals eat the plants for food
