Answer:
The acceleration is 
Explanation:
Given the velocity function:

you can obtain the instantaneous acceleration "a" as its first derivative:

To determine the value of "a" when the velocity was 12m/s, you need to figure out the value for "t" when this happens. At what time t is the velocity 12m/s?

This value of t is less than the 5 seconds mentioned in the text - so that is a good sign that the formula is valid for this value. And so you can use t=3.47s in the derivative (acceleration) above:
