It will take the cheetah 4 seconds to run 80 yards.
Step-by-step explanation:
Given,
Distance covered by Cheetah in 5/2 seconds = 50 yards
Ratio of distance to time = ![50:\frac{5}{2}](https://tex.z-dn.net/?f=50%3A%5Cfrac%7B5%7D%7B2%7D)
Let,
x be the time required to cover 80 yards.
Ratio of distance to time = 80 : x
Using proportion;
Ratio of distance to time :: Ratio of distance to time
![50:\frac{5}{2}::80:x](https://tex.z-dn.net/?f=50%3A%5Cfrac%7B5%7D%7B2%7D%3A%3A80%3Ax)
Product of extreme = Product of mean
![50*x=\frac{5}{2}*80\\50x=\frac{400}{2}\\50x=200](https://tex.z-dn.net/?f=50%2Ax%3D%5Cfrac%7B5%7D%7B2%7D%2A80%5C%5C50x%3D%5Cfrac%7B400%7D%7B2%7D%5C%5C50x%3D200)
Dividing both sides by 50
![\frac{50x}{50}=\frac{200}{50}\\x=4](https://tex.z-dn.net/?f=%5Cfrac%7B50x%7D%7B50%7D%3D%5Cfrac%7B200%7D%7B50%7D%5C%5Cx%3D4)
It will take the cheetah 4 seconds to run 80 yards.

The statements that are true from the graph are:
- The line is horizontal
- The line goes through (4, 4 )
- The y- values are all 4
<h3>Calculations and Parameters</h3>
Given the graph, we can note some things:
- There is a line with a slope of zero.
- This is a horizontal line parallel to the x-axis.
- The equation of the line is y = c
c is the value of the y- coordinates the line passes through.
The line passes through (0, 4 ) with a y- coordinate of 4
Therefore, the equation of the line of y= 4
