Rain is flowing into two containers at
9966 [12]

Given:

Volume of water in each container.

To find:

Difference in the rate of change.

Solution:

Take any two points on container 1.

Let the points are (10, 2) and (20, 4).

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{4-2}{20-10}

$m=\frac{2}{10}

$m=\frac{1}{5}

Rate of change for container 1 is \frac{1}{5}.

Take any two points on container 2.

Let the points are (5, 2) and (10, 4).

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{4-2}{10-5}

$m=\frac{2}{5}

Rate of change for container 2 is \frac{2}{5}.

Difference = \frac{2}{5}-\frac{1}{5}

                  $=\frac{1}{5}

The difference in the rate of change between the two containers is \frac{1}{5} gallon per minute.
