Answer(or question to Mentor): PROBLEM SOLUTION: The thunder is 6.4 miles away.
RATIONALE: If it takes 5 seconds for the thunder to travel 1 mile, and it traveled for 32 seconds, I divided 32 by 5 and got 6.4 seconds; since, the thunder travels 1 mile in every 5 seconds, it traveled 6.4 miles.

Thank you for submitting a response
I understand your calculation of 32 divided by 5 = 6.4, but make sure you are sonsistent with your units. In the problem solution you said 6.4 miles and in the rationale you said 6.4 seconds. Can you send me a response with what you would say your final answer would be?
I have another question, why did you choose to use division rather than multiplication?
Thanks again and I hope to hear from you soon.

I'd also like to see if you can try to work out the challenge problem.Thanks again and I hope to hear from you soon.

Answer(or question to Mentor): The reason I chose to divide instead of multiply, is because I wanted to first figure out how many sets of 5 seconds there were in 32 seconds. After I divided I found that there were 6.4 sets of 5 seconds in 32 seconds. Since, the sound travels 1 mile every 5 seconds and there are 6.4 sets of seconds in 32 seconds, I multiplied 6.4 seconds times 1 (1 = miles) and found that the thunder was 6.4 miles away.

Dr. Bowers, should I assume what that symbol stands for?? As in sets I mean? Or should I just straight go on responding? Thanks

Answer(or question to Mentor): RATIONALE: 1. Since there are 5280 feet in a mile, and it takes 5 seconds for sound to travel 1 mile I divided 5280 feet by 5 miles to see how many feet sound travels in 1 second. I found that sound travels at 1056 miles per second.
2. A. Since lightning strikes the earth 100 times per second, I multiplied 100 times 60 seconds, since there are 60 seconds in a minute and found that lightning strikes the earth 6000 times per minute.
3. Since lightning strikes 6000 times per minute, I multiplied 6000 times 60, since there are 60 minutes in a hour, and found that lightning strikes the earth 360,000 times per hour.
4. Since lightning strikes 360,000 times per hour, I multiplied 360,000 times 24, since there are 24 hours in a day, and found that lightning strikes the earth 8,640,000 times per day.

Answer(or question to Mentor): 5. Since lightning strikes 8,640,000 times per day, I multiplied 8,640,000 times 7, since there are 7 days in a week, and found that lightning strikes the earth 60,480,000 times per week.
6.Since lightning strikes 60,840,000 times per week, I multiplied 60,840,000 times 4, since there are 4 weeks in a month, and found that lightning strikes 241,920,000 times per month.
7.Since lightning strikes 241,920,000 times per month, I multiplied 241,920,000 times 12, since there are months in a year and found that lightning strikes the earth 2,903,040,000 times per year.
Sorry I couldn't send it all at 1 time so I sent it in peices. Mattie
