Full solution

Q. Every day at lunch, Hakim swims laps in the pool for one hour. The faster his speed, the more laps he is able to swim in the hour.

\newline

s =

the speed at which Hakim swims

\newline

l =

the number of laps Hakim is able to swim in one hour

\newline

Which of the variables is independent and which is dependent?

\newline

Choices:

\newline

(A)

l

is the independent variable and

s

is the dependent variable

\newline

(B)

s

is the independent variable and

l

is the dependent variable

Define Variables: In this problem, we need to determine the relationship between Hakim's swimming speed ( $s$ ) and the number of laps he can swim in one hour ( $l$ ). To do this, we need to understand the definitions of independent and dependent variables. $\newline$ An independent variable is one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
Identify Independent and Dependent Variables: Since Hakim's speed ( $s$ ) is what he can control or change, and the number of laps ( $l$ ) is the outcome or result of how fast he swims, we can determine that the speed at which Hakim swims is the independent variable. The number of laps he is able to swim in one hour is the dependent variable because it depends on his swimming speed.
Match Given Choices: Now, we can match our understanding with the given choices: $\newline$ (A) $l$ is the independent variable and $s$ is the dependent variable $\newline$ (B) $s$ is the independent variable and $l$ is the dependent variable $\newline$ Based on our reasoning, the correct choice is (B) $s$ is the independent variable and $l$ is the dependent variable.
