C 44 words per minute44 words per minute
D 36 words per minute
To find the constant of proportionality, we need to divide the number of words typed by the number of minutes it took.
The constant of proportionality is given by:
Constant of proportionality = Number of words typed / Number of minutes
In this case, the number of words typed is 368 and the number of minutes is 8.
Constant of proportionality = 368 / 8 = 46.
Therefore, the constant of proportionality that relates the number of words typed to the number of minutes it took is 46 words per minute.
Therefore, the correct answer is A. 46 words per minute.
