Question

If Ariana writes 6 pages in 2 minutes in a 50-page novel, what is the constant of proportionality, unit rate in one minute?

Answer 1

Let k be the constant of proportionality

Let p be the number of pages

Let t be the time taken

P ∝ t

p = kt

K = p/t

k = 6/2 = 3/1

The unit rate is 3 pages in one minute
