# The gallons of a water used to take a shower vary directly with the number of minutes in the shower. If an 8 minute shower uses 48 gallons of water, find the constant of variation?

To find the constant of variation, we divide $\frac{48}{8} = 6$.
That is, each minute in the shower uses $6$ gallons of water.
$\left(48 \text{gallons")/(8"minutes}\right) = 6$ gallons/minute
