For this case, we have that the equation of the position is given by:

To find the velocity, we must derive the equation from the position.
We have then:

Then, we evaluate the derivative for time t = 8.
We have then:
Answer:
the instantaneous velocity at t = 8 is:
4/5 to get a rational number bc it would be 5. hope it helps.
Um use fled but bfthb 123 tgbs
It’s gonna be the second option:)
