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: ->->->->->->->->->->->-> (start in the next line):
My guess of the ball’s average velocity is 7 cm/sec.
10 cm/sec + 4 cm/sec = 14 cm/sec
14 cm/sec / 2 = 7 cm/sec

Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Since I do not have a specific time interval to successfully find the average velocity, I instead subtracted the two rates and divided by 2 to get 7 cm/sec.

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: ->->->->->->->->->->->-> (start in the next line):
The distance the object has traveled after 3 seconds is 21 cm/sec.
7 cm/sec *3 sec = 21 cm/sec

At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The average rate of the velocity change with respect to clock time during this interval is 2.33 cm/sec.
7 cm/3 sec = 2.33 cm/sec

The change in velocity is not 7 cm. The number and the units are both incorrect.
