Hello I'm reposting this question because right now it's at the bottom and I don't think I will get an answer.

Assume that the follwing function gives the position of an object at time t. Find the velocity indicated by setting up and evaluating a limt algebraically.

s(t) = t, Find v(1).

I know that the answer is 1/2 because

s(t) = t = t(1/2)

s '(t) = (1/2)t^(-1/2) = 1/(2t)

s '(1) = 1/(21) = 1/2

But I can't get the answer by evaluating the limit algebraically.. can someone please show me the procedure?
