Mr. Fantastic, is the reasoning correct?

Did he mean $\displaystyle x^2$ or 2x?

To answer this question if 2x, it should be 2.

D = R * T $\displaystyle \implies $ R = $\displaystyle \frac {D}{T}$

Let D = y, R = R, and T = x

Let x = 0 be the initial and x = 3 be final

Then R = $\displaystyle \frac {\Delta Y} {\Delta X}$

Then ...

R = $\displaystyle \frac {0 - 6}{0 - 3} $

R = $\displaystyle \frac {-6}{-3}$

R= 2
