The position of an object at time t is given by s(t) = 1 - 12t. Find the instantaneous velocity at t = 2 by finding the derivative.

i really need help on this. Id appreciate it from anyone

OpenStudy (imstuck):

I believe that in order to solve this for t = 2 you need to fill the 2 into the derivative of the position equation (velocity) wherever you see a t. However, the derivative of you position equation is s'(t) = 12, and there are no more t's to fill into. Are you sure your position equation doesn't have a "^2" in it somewhere?
