1. 297 words in 5.5 minutes

(x) independent: _______________
(y) dependent: _______________
$\frac{y}{x}$ unit rate: _______________

Explanation:

Step1: Identify independent variable

The independent variable is the quantity that is controlled or changed. Here, time (minutes) is the independent variable as it does not depend on the number of words.

Step2: Identify dependent variable

The dependent variable is the quantity that depends on the independent variable. The number of words depends on the time spent, so it is the dependent variable.

Step3: Calculate unit rate

Unit rate is $\frac{\text{Number of words}}{\text{Time in minutes}}$, so substitute the given values.
$\text{Unit rate} = \frac{297}{5.5} = 54$

Answer:

(x) Independent: Time (minutes)
(y) Dependent: Number of words
$\frac{y}{x}$ Unit rate: 54 words per minute
