Answer(or question to Mentor): The answer to this question would be 6 and 2/5 miles away. I know this because you would divide the number thirty-two, the number of seconds counted, by five, the number of seconds that it takes for the sound of thunder to travel one mile. When you divide those numbers you get 6 and two fifths or 6 2/5.

Answer(or question to Mentor): Challenge Question #1 for Week #1:
I have figured out that the answer to the first challenge question is 1,056 feet per second. I think so because you divide 5, the number of seconds, it takes for sound to travel 1 mile, into 5,280. You divide it into 5,280 because 5,280 is the number of feet in a mile. When you do the division you get 1,056 feet per second.

Answer(or question to Mentor): Lillian,
The answer to b of the second challenge question is that lightning strikes 360,000 times per hour. I multiplied 60 times 60 first because there are 60 seconds in an minute and 60 minutes in an hour. I got 3,600, which is the number of seconds in an hour. Next I multiplied 3,600 times 100, the number of times that lightning strikes per second. My answer was 360,000; the answer to part b of the challenge question!

The answer to the third part of the 2nd challenge question is 8,600,000 times per day. I figured this out by multiplying 3,600 by 24, the number of hours in a day. You would get 86,400. THen I multiplied 86,400 by 100 the number of time lightning strikes per second. I got 8,640,00; the answer.
