Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes of all work;
- B completes of all work.
Hence, in 1 day both A and B complete of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If then that is impossible. So, B needs 15 days to complete the work alone.
