If it takes 16 faucets 10 hours to fill 8 tubs, how long will it take 12 faucets to fill 9 tubs?

The expression



is a constant, So we can calculate the constant from the first
situation.  The faucets are the "workers"

 =   = 20

Let the time required for 12 faucers to fill 9 tubs be T.  Then
for the second situation

 =   

It must also equal to the constant 20.

  = 20

Multiply both sides by 9

12T = 180

  T = 15 hours.
