Instantaneous velocity- super easy for anyone that knows calculus

[AerospaceEng]

Homework Statement

find the instantaneous velocity at 2.00s

Homework Equations

x=9.75+1.50t³

The Attempt at a Solution

I know that

lim x/t = dx/dt
t-0

So how do I go about solving the differentials.. basically I need a whole course on limits and differentials but i think if you show me how to get the answer i can learn quickly. Thanks
