You can put this solution on YOUR website! 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.
