If the bathtub holds a total of 46.2 gallons, how many minutes would it take to fill the entire tub? Write an equation in one va

sergejj [24]

Answer:

It will take 2.8 minutes

Step-by-step explanation:

Given

$x \to Minutes$

$y \to Gallons$

See attachment for complete question

Required

Time to fill the tube with 46.2 gallons

The attached table is a represents a direct proportional relationship between x and y.

This relationship is:

$y = kx$

Where k is the constant of proportionality.

When (x,y) = (1,16.5), we have:

$16.5 = k*1$

$16.5 = k$

$k=16.5$

So, we have:

$y = kx$

$y = 16.5x$

To calculate the required time to fill 46.2 gallons, we make x the subject

$x = \frac{y}{16.5}$

Where

$y =46.2$

$x = \frac{46.2}{16.5}$

$x = 2.8$
