Question

Aaron alone can finish a piece of work in 12 days and Brandon alone can do it in 15 days. If both of them work at it together, how much time will they take to finish it?

​

Answer 1

They will take to finish it in $\dfrac{60}{9}=\dfrac{20}{3}\ days$

Step-by-step explanation:

Since we have given that

Number of days Aaron can do a work = 12 days

Number of days Brandon can do a work = 15 days

According to question, we get that

$\dfrac{1}{12}+\dfrac{1}{15}\\\\=\dfrac{5+4}{60}\\\\=\dfrac{9}{60}$

They will take to finish it in $\dfrac{60}{9}=\dfrac{20}{3}\ days$
