Answer(or question to Mentor): The answer is 6 2/5 miles away. I divided 30 by 5 and got 6. Every five seconds is a mile away, so five goes into 30 6 times. There are 2 miles left so there is 2/5 of a mile left.
challenge questions
1.The answer is 1,056. Sound travels one mile every five seconds, so I divided 5 into 5,280. There is 5,280 feet in a mile.
a.The answer is 6,000. There are 60 seconds in a minute and lightning strikes 100 times a second, so I multiplied and got 6,000.
b.The answer is 360,000. There is 60 seconds in a minute and 60 minutes in an hour. I multiplied those 2 numbers together and got 3,600. Then I multiplied 100 by 3,600 and got 360,000.

Answer(or question to Mentor): c.The answer is 8,640,000 times lightning strikes in a day. I knew that lightning strikes 360,000 every hour, so I multiplied 360,000 by 24 because there are 24 hours in a day and got 8,640,000.
d.The answer is 60,480,000 times lightning strikes in a week. I knew that lightning strikes 8,640,000 times in a day, so I multiplied 8,640,000 by 7 because there are 7 days in a week and got 60,480,000.
e.The answer is 259,200,000 times lightning strikes in a month if there are 30 days in that month. I knew that lightning strikes 8,640,00 times in a day, so I multiplied that by 30 and got 259,200,000.
f.The answer is 2,913,600,000 times lightning strikes in a year. I knew that lightning strikes 8,640,000 times a day, so I multiplied that by 365 since there are 365 days in a year.

Mentor Reply: Hi Andrew,
Great job in explaining your answers. The answer of 6 2/5 is correct for the first problem. I can see that you also finished up the challenge problem today. I got a different number for part f. of the challenge problem. Your steps are right on target. Can you try multiplying again? Hope to hear from you soon.
Sincerely, Andrea
