The problem:
Here is the definition of rate of change of one quantity with respect to another:
The average rate of change of A with respect to B on an interval is
average rate of change of A with respect to B = (change in A) / (change in B)
Apply the above definition of average rate of change of A with respect to B to each of the following. Be sure to identify the quantity A, the quantity B and the requested average rate.
If the position of a ball rolling along a track changes from 10 cm to 20 cm while the clock time changes from 4 seconds to 9 seconds, what is the average rate of change of its position with respect to clock time during this interval? .5 cm with .444 seconds
answer/question/discussion:
If the velocity of a ball rolling along a track changes from 10 cm / second to 40 cm / second during an interval during which the clock time changes by 3 seconds, then what is the average rate of change of its velocity with respect to clock time during this interval? .0205cm/sec
answer/question/discussion:
If the average rate at which position changes with respect to clock time is 5 cm / second, and if the clock time changes by 10 seconds, by how much does the position change? .5cm/second
answer/question/discussion:
You will be expected hereafter to know and apply, in a variety of contexts, the definition given in this question. You need to know this definition word for word. If you try to apply the definition without using all the words it is going to cost you time and it will very likely diminish your performance. Briefly explain how you will ensure that you remember this definition. I know I will remember it because I have wrote this formula down in my notes.
answer/question/discussion:
You are asked in this exercise to apply the definition, and given a general procedure for doing so. Briefly outline the procedure for applying this definition, and briefly explain how you will remember to apply this procedure. I tried doing this to the best of my ability but am not sure if I done it right. I may have gotten the variables mixed up.

I would like to know if I done this correctly. If not please send my examples of right ones and how to obtain the answer.
You are giving answers without any indication of how you found them or reason them out. You need to describe the details of your reasoning and other calculations, as opposed to simply giving a final answer. Without that information I can tell if you got a correct answer by the necessary reasoning, or alternatively what is is you are giving incorrectly to get an incorrect answer.
Please run through this exercise again and explain your reasoning, and gave the details other calculations as well as your final answers.
In order to distinguish between the questions in the answers, your answer should follow the answer/question/discussion: prompt.
