Question

A dripping faucet waste a cup of water if it drips for 4 minutes the amount of water wasted varies directly with the amount of time the faucet drips what is the constant of variation

Answer 1

'the amount of water wasted varies directly with the amount of time the faucet drips'

in other words, directly proportional , if time increases, so does water wasted

\[\large water~ wasted [w]~~~\alpha~~~time~running[t]\]
\[\Large W~~\alpha~~t\]

Answer 2

To make an equation , you need a proportion constant, k

W = k * t

They gave you one point ( t , W) = (4min , 1 cup), use that to figure the constant k
