A particle moves along the curve y=3x2+6x8\displaystyle {y}={3}{x}^{{2}}+{6}{x}-{8} in such a way that as it moves, dxdt=8\displaystyle \frac{{{\left.{d}{x}\right.}}}{{{\left.{d}{t}\right.}}}={8} units/minute.

When the particle reaches the point (7, 181) it is moving the origin at a rate of units/minute. (Enter your answer rounded to 3 decimal places)
