what's constant rate?
its in the 2004 paper mc q 21?
(oh but it doesn't refer to it, it's in the success one book, in the answers)

It's really to do with the "constant of proportionality".

For that question, t ∞ 1/n or t = k/n, where k is the constant of propotionality.

t = k/n is the general equation for a hyperbola, so the graph must be D.
It can't be C because n and t cannot be equal to 0.

Hope that helps.
