Answer:
Alex can do the job in 60 days alone.
Step-by-step explanation:
Alex and Brandon working together, they can finish the job of cleaning the school in 15 hours. Brandon alone in 20 hours can finish the job.
So, Brandon can complete part of the job in one hour.
Let, Alex alone can finish the same job in x hours.
So, Alex can complete part of the job in one hour.
So, working together they do part of the whole job in one hour.

⇒ 5x = 300
⇒ x = 60 days.
Therefore, Alex can do the job in 60 days alone. (Answer)
