The given rational function that gives the average rate of water entering

the pool is the total volume in the pool divided by the time.

Response:

The numerator of the rational expression represents the;

A. Total number of gallons of water in the kiddie pool

The denominator of the rational expression represents the;

B. Total number of minutes of filling the kiddie pool

The given parameters are;

[tex]Expression \ for \ average \rate \ of \ water \ entering \ the \ pool = \mathbf{ \dfrac{2 \cdot x + 6 \cdot (x + 3)}{2 \cdot x + 3}}[/tex]

The parts of the given expression can be analyzed as follows;

x = The time in which the second hose is in use

2 = The flow rate of the second hose in gallons per minute

6 = The flow rate of the first hose in gallons per minute

x + 3 = The time in which the first hose is in use

x + x + 3 = 2·x + 3 = The total number of minutes of filling the kiddie pool

Therefore;

2·x = The volume added to the pool due to the second hose

6·(x + 3) = The volume added to the pool due to the first hose

2·x + 6·(x + 3) = Total number of gallons of water in the kiddie pool

Which gives;

The numerator of the rational expression represents the;

A. Total number of gallons of water in the kiddie pool

The denominator of the rational expression represents the;

B. Total number of minutes of filling the kiddie pool
