Answer:
Explanation:
To determine how long it would take the helper alone to complete the job, we need to know the time it takes for the helper and the person being helped together to complete the job.
1. The given information states that it takes 3 hours for both the helper and the person being helped to complete the job.
2. To find the time it would take the helper alone, we need to subtract the time it takes for both of them from the total time. In this case, we subtract 3 hours (time for both) from the total time.
3. Subtracting 3 hours from the total time, we get 3 hours - 3 hours = 0 hours.
4. Therefore, it would take the helper alone 0 hours to complete the same job.
