The problem:
A ball starts with velocity 4 cm/sec and ends with a velocity of 10 cm/sec.
What is your best guess about the ball's average velocity?
answer/question/discussion: 7 cm/sec
Without further information, why is this just a guess?
answer/question/discussion: because the end time was not given
If it takes 3 seconds to get from the first velocity to the second, then what is your best guess about how far it traveled during that time?
answer/question/discussion: 18cm
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: 2cm/s/s
