Answer:
hours
Step-by-step explanation:
Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.
As per given , we have
x+y= 8
Since : ![Distance = Speed\times Time](https://tex.z-dn.net/?f=Distance%20%3D%20Speed%5Ctimes%20Time)
So , we have
20x+12y=122
According to the given question , we have the following system of equations ,
![x+y= 8--------(1)\\\\20x+12y=122------------------(2)](https://tex.z-dn.net/?f=x%2By%3D%208--------%281%29%5C%5C%5C%5C20x%2B12y%3D122------------------%282%29)
Multiply 12 on both sides of equation (1) , we get
![12x+12y=96------------(3)](https://tex.z-dn.net/?f=12x%2B12y%3D96------------%283%29)
Eliminate equation (3) from (2) , we get
![8x=26\\\\\Rightarrow\ x=\dfrac{13}{4}=3\dfrac{1}{4}](https://tex.z-dn.net/?f=8x%3D26%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B13%7D%7B4%7D%3D3%5Cdfrac%7B1%7D%7B4%7D)
Hence, you felt
hours good.
