540 divided by 12 is 45

45 divided by 5 days in a work week is 9 weeks

a work week don't consist of weekends

Answer 2

It will take twelve (12) plumbers 9 weeks to install the same number of lines

From the question,

We have that, 18 plumbers can install 540 water lines in 6 weeks,

To determine how long it will take 12 plumbers to install the same number of lines,

First, we will determine how long it will take 1 plumber.

If 18 plumbers can install 540 water lines in 6 weeks

Then,

1 plumber will install 540 water lines in 18 × 6 weeks

18 × 6 weeks = 108 weeks

∴ It will take 1 plumber 108 weeks to install 540 water lines

Now, for the number of weeks it will take 12 plumbers

If 1 plumber can install 540 water lines in 108 weeks

Then,

12 plumbers will install 540 water lines in $\frac{108}{12}$ weeks

$\frac{108}{12} = 9 \ weeks$

Hence, it will take twelve (12) plumbers 9 weeks to install the same number of lines
