Answer(or question to Mentor): The answer is 6.4 miles. I got this from dividing 32 by 5 because 32 seconds is how many seconds between the thunder and lighting and 5 seconds equals a mile.

Good job! You've got the right answer Aubrie! However, I just want to tell you that 5 seconds is not equal 1 mile, but it is how many mile the thunder travels in 5 seconds. Just be careful of the wording, Aubrie. You've done a good job for your first problem, so go and challenge yourself with the challenge problems. I'm waitting to read your solutions for those problems.
Bye bye, Aubrie

Answer(or question to Mentor): The answer to challenge question number 1 is 156 ft per second. I got this because there are 5,280 ft are in a mile and it takes 5 seconds for sound to travel a mile. I divided 5,280 by 5.
I know that I did not do this question right. Please help me on this one.

Instructor Comments:
Cam,
Aubrie's explanation would not be considered "conceptual." There is no indication of why he chose to divide. Also, although we talked about correcting the students on their wording of 5 seconds not equaling 1 mile, I can see that so many students did this that it would not be consistent to correct just him. So, let that one go, but push him to explain why he divided. You can say something like, "Congratulations, your numerical answer is correct. However, one of the requirements of solving these problems is that you explain WHY you chose to solve the problem as you did. SO, suppose that you wanted to explain your thinking to a friend in your class who was confused. Can you find a way to explain why division makes sense?"
Also, you have a spelling error: waiting only has one t.

One more thing: I just noticed after hitting the submit button that Aubrie did attempt the challenge problem. So, revise your last statement to address this submission as well. As you can see, his explanation here is helpful in showing you where his mistake was: it appears that he was reasoning correctly and simply has a computational error.

Congratulations! Your answer to the original problem is correct. However, you did not explain why you divided 32 by 5. Can you find a way to explain why did you use division to solve your problem so that another student who did not attend class that day would understand?
Your answer to the first challenge problem is incorrect; nonetheless, your reasoning is indeed correct. You just have a computational error. Now, you only need to divide 5280 by 5 over to obtain the right answer. You should challenge yourself with the second challenge problem. I'll wait to read your revision and your solutions for the second challenge problem.
Bye Aubrie

The answers to challenge question number 2 are:
A. 6,000 times per minute
B. 360,000 times per hour
C. 8,640,000 times per day
D. 60,480,000 times per week
I will complete the rest soon
Thanks!

Congratulations! Your answer to the original problem is correct. However, you did not explain why you divided 32 by 5. Can you find a way to explain why chose to use division to solve your problem so that another student who did not attend class that day would understand?
Your answer to the first challenge problem is incorrect; nonetheless, your reasoning is indeed correct. You just have a computational error. Can you re-check your math and resubmit your answer
I also encourage you to try the second challenge problem. I am looking forward to reading your revised explanation, your revised computation for the first challenge problem, and your solutions for the second challenge problem.
