To find the constant of proportionality, we can set up a proportion using the given information.
Let x represent the constant of proportionality.
320/40 = x/1
Multiplying both sides of the equation by 40, we get:
320 = 40x
Dividing both sides by 40, we get:
x = 8
Therefore, the constant of proportionality is 8.
