Answer(or question to Mentor): I think the ansewer is 6 2/5.
First I took five and counted by fives to get up to thirdy
(which is 6 miles)
Then I had two more seconds left so I took two out of five that would be 2/5.
So the ansewer is 6 2/5.
I also counted by fives because the sound of thunder to travel one mile is five seconds.

Answer(or question to Mentor): Its me Kayla. Sorry I did not put my name on the last problem. Anyway I think the answers to the challenge questions are
1. 5,280 ft.
2. a.per minute-60x100=6,000
b.per hour- 60x6,000=360,000
c.per day- 24x360,000=8,640,000
d.per week- 7x8,640,000=60,480,000
e.per month-4x60,480,000=241,920,000
f.per year-12x241,920,000=2,903,040,000

Mentor Reply: Hi Kayla,
Don’t worry, I got your answer for the first problem and I knew it was from you. You were correct in believing that the answer was 6 2/5. The way you solved the problem was very easy for me to follow. The only think you forgot to tell me was what 6 2/5 represents.
I also reviewed you answer to the challenge question. You might want to look over the answer you gave for #1. It’s not correct. Remember that you are to use the information from the first problem.
Your answers for #2 (a-f) are correct however, can you be more specific and tell me how and why you used these numbers to solve the problems?
I’ll be looking forward to your explanation and a new answer for #1 to the challenge problem.
Sincerely,
Angelica

Instructor Comments: Angelica,
I like the way that you said that you addressed her concern about not putting her name on her submission. I think this was a fabulous submission, and would praise her for being thorough and explaining it in a way that another student could understand it-- this differs from saying that it was easy for YOU to follow because the goal should be for them to write an explanation that other peers could follow, not that you, or the teacher, could follow. The psychology here is that we want them to not think of the teacher (or mentor or other adult) as the sole arbitors of correct or acceptable answers.
Alas, you are correct that she didn't include the units. Instead of assuming that she "forgot" to tell you the units, I would be direct and say something like "Your numerical answer of 6.4 is correct, and your explanation was outstanding. However, in order for the answer to be completely correct, we need to know what 6.4 measures. Please include the units and then resubmit your answer and explanation." Also, encourage her to do the challenge problem.

Answer(or question to Mentor): Sorry.The answer for number one is 1,056 ft. What I did was I took how much feet were in a mile and that is 5,280. Then I took 5,280 and divided it into 5 because it said how far does sound travel per second and 5 seconds are in a mile. So I got 1,056 ft.
For problem number 2 I took
a.per minute and thier is 60 seconds in a minute and times that by 100 because lightning struck 100 times per second. Then I took the answer to that and multiplied that by 60 because thier is 60 minutes in a hour. Third I took that answer and multiplied that by 24 because there is 24 hours a day. Fourth I took the answer to that and multiplied that by 7 because there is 7 days in a week. Fifth I took that answer and multiplied it by 4 because there is 4 weeks in a month. Sixth I took that answer and multiplied it to 52 because there is 52 weeks in a year and that is how I got my answer. Oh! It is 6 2/5 seconds.

Mentor Reply: Hi Kayla,
Their is no reason to apologize, we all seem to overlook items from time to time.
The answer to #1 that I was looking for was that 6 2/5 represented 6 2/5 Miles.
If you see a lightning bolt and it takes 32 seconds for you to hear the sound of thunder and you are given that the sound of thunder travels 5 seconds per mile. Then the lightning bolt would be 6 2/5 miles away.
Once again, your explanation for the challenge problem was very clear. Yet I too overlooked that 2f was not totally correct. From your 1st response, I can see you multiplied the total for the month by 12 (12 because there are 12 months in a year.) Your answer was 2,903,040,00 per year. But in your second response, you multiplied 52 by the amount for the month. To be completely correct, you should have multiplied the total per week (60,480,000) by 52 weeks (Remember that each month does not always have exactly 4 weeks) The correct answer would be:
60,480,000 x 52 = 3,144,960,000 per year.
Overall, you did a great job.
I’ll be awaiting your response to the next problem.
Sincerely,
Angelica
