The constant of proportionality for her typing rate per minute is 53 words per minute.
Given the following data:
- Number of words = 424 words
To determine the constant of proportionality for her typing rate per minute:
In this exercise, you're required to solve for the constant of proportionality for the rate at which Brady type with respect to time. Since the rate at which she type is directly proportional to time, we would divide the number of words by the time it took.
[tex]k=\frac{Nummber\;of\;words}{Time} \\\\k=\frac{424}{8}[/tex]
k = 53 words per minute.
