How many days would it take an ostrich to get across Australia from the most eastern point to the most western point twice?

1.  Background Story:
 How many days would it take an ostrich to get across Australia from the most eastern point to the most western point twice? This seems like an odd, random question, but that's why I chose it. Ostriches are fairly fast animals so why not wonder how fast they really are?



2.  Ask Yourself This:

Five questions that you will need to answer to find out How many days would it take an ostrich to get across Australia from the most eastern point to the most western point twice.
1. How many miles is Australia from the farthest point on one end the the farthest point on the other (horizontally)?
2. How long can an ostrich walk before it needs to rest, eat, or drink?
3. How far can an ostrich run in one hour?
4. What is the fastest sustained time ostriches can run?
5. How long does no ostrich need to eat nod sleep per day?

3. Helpful Hints:

a.Here are the answers I found to my questions.
1.4,100 kilometers (http://www.skwirk.com.au/p-c_s-4_u-307_t-751_c-2815/geographical-dimensions-size-and-shape/nsw/geographical-dimensions-size-and-shape/australia-s-physical-environment/the-australian-continent)
2.Ostriches are like camels and can go long periods with no water. (2-3 same source)
3.31 miles per hour (50 kilometers) (http://animals.sandiegozoo.org/animals/ostrich)
     4. The average sustained time and ostrich can run is 31MPH. (www.ostriches.org/faq.html-AmericanOstrichAssosiation-frequentlyaskedostrichquestioons)
     5. (See estimation)

b.I estimate that and ostrich will need about two hours of sleep per day and they feed on herbs that they find so it could get its own food, I would guess about 1 more hour per day for eating. That would be an extra three hours per day to however long it would take the ostrich to run the distance.




4.  Construct a Formula:
m=miles    h=hour    /=divided by   ~=converted into   km=kilometers   d=days

   Formula: km~m \ mperh x 2+3d

Formulas described in words:
kilometers converted into miles divided by the miles per hour multiplied by two plus 3 multiplied by the amount of days it took

(kilometers=length of Australia from most eastern to most western points)


5.  Messy Math:
4100km~2547.621miles   2547.621m/31mperh=82.181322h
82.181322h*2=164.36264h
164.36264h~6.848d  (6.848d rounded to 7d) 3h*7d=21h
7d+21h= 7days and 21 hours

It would take an ostrich about 7 days and 21 hours to run across australia twice.

(Technically you can not change this number into SN)





6.  Answer:
It will take an ostrich 7 days and 21 hours to walk across Australia from the most western point to the most eastern point twice. This is amazing because looking on the internet I found that the average sustained speed of the fastest human alive is 23 miles, about two thirds of an ostriches. this means it would most likely take a human more than 10 days if you include the time they need for resting and eating.
