Mentor Reply: Hi Erin,
I appreciate your response to the problem. Congratulations! Your answer is correct. However, your explanation states that you divided 32 seconds by 5 seconds. This would not give an answer in terms of miles. Please check the units for the 5.
In addition, we are going to post some of the really clear explanations, so I was wondering if you could elaborate on why you divided.
Once you have finished your explanation, why don’t you try the challenge questions, they are fun to solve.
Sincerely, Maria Alvarez

Answer(or question to Mentor):
Challenge: 1. .2 miles per second
2. a. 6000
b. 360000
c. 8640000
d. 60480000
e. 259200000
f. 94608000000
Rationale: To get part one, I divided 6.4 miles by 32 seconds to get .2 miles per second. To get number two, part a, a multiplied 100 times per second by 60 seconds to get 6000 times per minute. On part b, I multiplied 6000 times per minute by 60 minutes to get 360000 times per hour. On part c, I multiplied 360000 times per hour by 24 hours to get 8640000 times per day. On part d, I multiplied 8640000times per day by 7 days to get 60480000 times per week. On part e, I multiplied 8640000 times per day by 30 days to get 259200000 times per month. On part f, I multiplied 259200000 times per month times 12 months to get 94608000000 times per year.
