ds/dt is the velocity.
Assuming you meant
s(t) = 3t^2 + 5t + 3
ds/dt = 6t + 5
so plug in t=5.

Hi Steve, can you show me step by step how to factor this, because my numbers compared to the correct numbers are way too low and I don't know what I'm doing wrong.

how to factor what?
ds/dt at t=5 is just
6*5+5 = 35
ds/dt at t=5 is just
6*5+5 = 35
