Sam can type 368 words in 8 minutes. What is the constant of proportionality that relates the number of words typed, y , to the number of minutes it took to type, x ? (Remember that constant of proportionality is k = yx)
To find the constant of proportionality, we divide the number of words typed, 368, by the number of minutes it took to type, 8.
k = 368/8 = 46
So, the constant of proportionality is 46.
