Answer(or question to Mentor): I know that 5 seconds equals 1 mile. So I divide 5 into 32. So the answer would be 6.4 because 5 go into 32, 6 times. There is 2 left over and I figure the percentage and get 6.40 which is 6.4.

Answer(or question to Mentor): If sound travels a mile in 5 seconds I divide 5 into 5,280 because I know that 5,280 are the feet in a mile. The answer comes out to be 1,056.

Mentor Reply: Dear Leland,
You did a great job at solving the lightening problem. Can you tell me what you have 6.4 of? Also, I'm not clear on how you got .4 from the left over 2, so can you explain this to me? Your answer of 1,056 feet per seconds on Challenge problem 1 is explained clearly. Now you can try to work on the next part of the Challenge problem, which deals with more conversions. Good luck.

Instructor Comments:
Corrie,
Outstanding points. My only comment is that you might want to consider encouraging Leland to write so that his CLASSMATES could understand what he was thinking. This differs from saying "can you tell ME ... and I'M not clear..." The psychology here is that we hope to encourage these students to be arbitors of good answers, rather than relying on adults to always have the final say!

Mentor Reply: Dear Leland, You did a great job at solving the lightening problem. It may help to write your explanation as if you were explaining it to your classmates. For instance, telling them what you have 6.4 of and how you got .4 from the left over 2? Also, I can see what you did to solve the first part of the challenge problem. Now you can try to work on the next part of the Challenge problem, which deals with more conversions. Good luck. Corrie

Answer(or question to Mentor): The answer is 1.4. I divide 60(which I know that there is 60 seconds in to a minute) and 100(which is the seconds it hits) and I get 1.4. I got the 4 because forty is left over and forty into one hundred is forty I think.

Mentor Reply: Dear Leland,
Thank you for submitting an answer to the Challenge problem. You did a good job at explaining how you got your answer. However, you may need to try it again. If lightening strikes the earth 100 times per second, wouldn’t lightening strike the earth more than a 100 times a minute because there are 60 seconds in a one minute?
Also, can you explain to me, as if I was one of your classmates, what you have 6.4 of in the lightening problem. Keep up the hard work.
