One member of a gardening club can plant flowers in 12 hours. With two members of the club working together the job can be done

mariarad [96]

Answer:

24 hours

Step-by-step explanation:

One member of the gardening club can alone plant flowers in 12 hours.

So in 1 hour he can plant 1/12 of the flowers.

Let the time required by the second member of the club to plant flowers alone be x hours.

Then in 1 hour he can plant 1/x of the flowers.

Now when the two members work together,each hour they can plant:

$\frac{1}{12}+\frac{1}{x}$ of the flowers.

But they can together complete the job in 8 hours. So in one hour they plant 1/8 of the flowers.

=> $\frac{1}{12}+\frac{1}{x}=\frac{1}{8}$

=> $\[\frac{1}{x}=\frac{1}{24}\]
$

=> x=24

So the second member can plant the flowers alone in 24 hours
