Alice the Ant Scales the Burj Khalifa
Alice the ant is climbing to the top of the tallest manmade structure in the world...the Burj Khalifa, a Dubai skyscraper that is 2,722 feet in height.
Alice is 7 mm's in length, and on each of her steps, she moves 1.5 mm.
Question 1: How many steps will Alice take in climbing from the base of the Burj Khalifa to its top?
Question 2: If Alice can take 5 steps in a second, how long will it take Alice to reach the top? (Pick an understandable time unit when expressing your answer)
Question 3: If Alice enticed her fellow ants to join her in a single line endtoend, how many ants would it take to span the entire length of the Burj Khalifa?
Question 4: To answer Question #3, did you start from scratch or use a proportion involving your answer from Question #1?

Hint: How many steps will Alice take in moving 1 foot?
Remember to convert...millimeter vs. feet.
Solution Commentary: Question 1: A great many!
Question 2: A long time!
Question 3: A great many!...butI wonder how they can arrange themselves into a styraight line...as a deviance of even 1 degree will have a large impact!
