The problem:

A ball accelerates at 8 cm/s^2 for 3 seconds, starting with velocity 12 cm/s.

What will be its velocity after the 3 seconds has elapsed? 

answer/question/discussion: 12 cm/s + (8 cm/s^2)(3s) = 36 cm/s

Assuming that acceleration is constant, what will be its average velocity during this interval? 

answer/question/discussion: (36 cm/s + 12 cm/s)/2 = 24 cm/s

How far will it travel during this interval?

answer/question/discussion: 72 cm/s
