A.) h(3) – h(0)
B.) h(3/3)-h(0/3)
C.) h(3)/3
D.) h(3)-h(0)/3

I would LOVE to pick "D.", but you have written it incorrectly, so it is no longer the correct answer!

._. i tried the best i could to write it out.

do you understand how to do this problem?

No i do not.

You did not try the best you could.  You could have added parentheses and done it correctly.

D.) (h(3)-h(0))/3

Done!  Now, the answer is D.

h(3) is the location at time t = 3 - When we quit watching.
h(0) is the location at time t = 0 - When it started.
h(3) - h(0) is the total change in location.
3-0 = 3 is the time it took to change that much.
So, [h(3) - h(0)]/3 is the average change over the 3 seconds that we cared about it.
