Answer:
it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
Let t is the time (t >0)
We have:
- 1st person working rate per one task: 1/t-8
- 2nd person working rate per one task: 1/t
- Working rate per one task from 2 person: 1/3
<=> 1/3 = 1/t + 1/t-8
<=>
<=> ![(t-7)^{2} =25](https://tex.z-dn.net/?f=%28t-7%29%5E%7B2%7D%20%3D25)
<=> t - 7 = 5
<=> t = 12
So it takes 1st person 4 hour and second person is 8 hours
