One person can complete a task 8 hours sooner than another person. Working together, both people can perform the task in 3 hours. How many hours does it take each person to complete the tasking working alone?

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 = 5

<=> t = 12

So it takes 1st person 4 hour and second person is 8 hours
