Answer(or question to Mentor): Dear, mentor
I think the awnser is 160 miles away because thunder travels five miles a second so I multiplied 32x5 and got my awnser.

Answer(or question to Mentor): I think the awnser is E because the thing is that if lightining strikes a hundred strikes a month it would be more reasonable that if it strikes a day or a week it might be possible but I dont know the awnser but that is my hypothesis

Mentor Reply: Joel, you have a good start to your responses. Origional problem: Your attempt was good but your answer is incorrect. I do not understand why you multiplied 32x5. Can you please clarify and write back. Challenge 2a: Good attempt Joel, but your answer is wrong. Explian to me how you got your answer. Did you multiply? If so, why? What were you finding out by multiplying? How many seconds are in a minute? These are all questions that will help you to understand the problem and to help you to get the correct answer. I look foreward to your revision.
Challenge 2c,d,e: You assumption that it is more likely for lightning to strike 100 times a month, rather than 100 times a day or week, is valid. Your assumption is not correct, but it is surprising that lightning strikes somewhere on the surface of the earth 100 times a second. Your answer (E) is incorrect. To find out how many times lightning would strike per day, you must first know How many times lightning strikes per second (100). Then you are going to need to find out how many strikes per minute, and hour, so that you can more easily find how many times lightning strikes per day. Take some time to figure this out. Try multiplication. Once the number of strikes per day is found, you can then find how many per week and month. Think about using conversions to go from seconds to minutes, minutes to hours, etc. This should help you get a better idea of what the question is asking. Thank you for your responses and I look foreward to your revised responses. Sincerely, Erik

Instructor Comments:
Erik,
This is a difficult case! I realize it is hard to write something positive since all of his answers are incorrect. I think the best thing to do is probably to simply say the positive thing that you said up front, and then be direct and say that the answer is incorrect For example, in the original question (by the way, you have a spelling error on "origional"), you could say "YOu did a good job of explaining how you thought about the problem, but this was an incorrect answer. When you multiply, you are finding 5 sets of 32, but that is not what you are trying to find." or some hint like that.
In addressing each of his challenge responses, you might want to add the paragraph breaks so that it is easier to read the sections. Your hints are good.
