If Alex and Brandon work together, they will finish cleaning the school in 15 hours. Working alone, Brandon can finish the same

andriy [413]

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 $\frac{1}{20}$ part of the job in one hour.

Let, Alex alone can finish the same job in x hours.

So, Alex can complete $\frac{1}{x}$ part of the job in one hour.

So, working together they do $(\frac{1}{20} + \frac{1}{x}) = \frac{x + 20}{20x}$ part of the whole job in one hour.

Hence, from the conditions given we can write

$\frac{x + 20}{20x} = \frac{1}{15}$

⇒ 15x + 300 = 20x

⇒ 5x = 300

⇒ x = 60 days.

Therefore, Alex can do the job in 60 days alone. (Answer)
