Answer:
Hello, unit rate of this problem is:
[tex]unit rate = 72 \frac{words}{minute}[/tex]
Step-by-step explanation:
To solve this problem, you can use the rule of three.
To build the equations of the system, we must analyze the information given:
[tex]3,528(words) = 49 (minutes)[/tex] ... (1)
and we want to find number of words per minute
[tex]x (words) = 1 (minutes)[/tex] ...(2)
Therefore, by the rule of three
[tex]3,528(words) = 49 (minutes)[/tex]
[tex]x (words) = 1 (minutes)[/tex]
Thus, multiplying in a cross, we have:
[tex]49*x = 3,528*1[/tex]
[tex]x = \frac{3,528}{49}[/tex]
[tex]x = 72[/tex]
Lastly, replacing the value of x in (2), we have:
[tex]72 (words) = 1 (minutes)[/tex]
By definition, unit rate compares two units, and it's the ratio of then, for this reason:
[tex]\frac{words}{minutes} = \frac{72}{1} \frac{words}{minutes} = 72 \frac{words}{minutes}[/tex]
