Physics problem find initial velocity

Given the equation of the moving body s=3t2+2t+1 (in SI units), find its initial velocity (at t=0).

Correct answer: 2 m/s

I'm confuused. For t=0, s will be 1, not 2. I'm assuming s is the speed in m/s and t is the t. The 1 at the end represents the speed at t=0.

Robert, s(t) is typically displacement as a function of time, not speed.
