Question

read the description of a proportional relationship. during hockey season, ellie stays in excellent shape. to keep up her conditioning in the off - season, she swims every day. there is a proportional relationship between the time (in seconds) ellie swims freestyle, x, and the number of feet she travels, y. the equation that models this relationship is y = 3x. how long does ellie need to swim to travel 12 feet? write your answer as a whole number or decimal.

Explanation:

Step1: Identify the given equation

The equation is $y = 3x$, where $y$ is the number of feet traveled and $x$ is the time in seconds.

Step2: Substitute the value of $y$

We know $y = 12$ feet. Substitute $y = 12$ into the equation $12=3x$.

Step3: Solve for $x$

Divide both sides of the equation $12 = 3x$ by 3. So $x=\frac{12}{3}=4$.

Answer:
