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.

Morgarella [4.7K]
<h2>The work of Charles Darwin and Alfred Wallace </h2>

Explanation:

C) uniform modification of genetic traits over long periods of time.

The theory of uniformitarianism  states that the natural phenomena and laws that are bringing about changes in the today's world are functioning in the same rate since the geological times. This idea of uniformitarianism was linked to biological sciences because according to Darwin and Wallace's observation, the uniform modification of genes among the population brought about the species diversity on the Earth.
