Q. Every day at lunch, Carly swims laps in the pool for one hour. The faster her speed, the more laps she is able to swim in the hour.\newlines=s = the speed at which Carly swims\newlinel=l = the number of laps Carly is able to swim in one hour\newlineWhich of the variables is independent and which is dependent?\newlineChoices:\newline(A) ll is the independent variable and ss is the dependent variable\newline(B) ss is the independent variable and ll is the dependent variable
  1. Define Variables: In any function or relationship between two variables, the independent variable is the one that is chosen or controlled by the experimenter or the one that influences the other variable. The dependent variable is the one that depends on the independent variable and changes in response to it.
  2. Carly's Example: In the context of Carly swimming laps in the pool, her speed ss is something she can control or choose. She can decide to swim faster or slower. The number of laps ll she is able to swim in one hour depends on how fast she swims. Therefore, the speed at which Carly swims is the independent variable, and the number of laps she can swim is the dependent variable.
  3. Answer Explanation: Based on the understanding of independent and dependent variables, we can now answer the question. Since Carly's speed (ss) is the independent variable and the number of laps (ll) is the dependent variable, the correct choice is:\newline(B) ss is the independent variable and ll is the dependent variable.
