Hi. Is the (.2t-1) supposed to be squared anywhere due to acceleration being rated with respect to time squared...? If not, all you have to do is create an equation:
Then, you factor out all those parts within the parenthesis to that 12.5, giving you:
Move all non-t values to the numerical side:
divide both sides by the coefficient of the variable t, and that will be your time, 7.186
