Lila is a track and field athlete. She must complete four laps around a circular track. The track itself measures 400 meters fro
tekilochka [14]

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

Explanation:

Formulae :\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}

\text{Velocity}=\dfrac{\text{Displacement}}{\text{Time}}

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, \text{Speed}=\dfrac{1600}{360}=\dfrac{40}{9}m/s

= 4.44\ m/s

But from start to finish displacement = 0 m   [displacement is the shortest distance between starting point to the finishing point]

So, \text{Velocity}=\dfrac0{360}=0\ m/s

Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.

Iteru [2.4K]
The answer is cancer.
Cancer is an uncontrolled division of cells. The regulation of cell cycle is necessary for normal cell division. The first phase of the cell cycle is the G1 phase. If the G1 phase is affected, mistakes in this process lead to the uncontrolled division of cells called cancer.
