1. The problem statement, all variables and given/known data
Estimate the length of the Sydney Harbour Bridge that lies between the pylons. Give your
answer in metres and give a justification for your answer.
2. Relevant equations
No equations needed I guess. To answer this type of question you need to consider extreme values and then "zoom in" to an appropriate answer.
3. The attempt at a solution
I'm really having trouble with this question. What does extreme values mean? Are they just random values?
Here's the sample solution....But I still can't figure it out why the question is solved this way.By what factor do the 2 values change in each row????
1 mm < distance < 100 km
1m < distance < 10 km
10 m < distance < 5 km
100 m < distance < 1 km
200 m < distance < 1 km
Estimate of distance between pylons of Sydney Harbour Bridge is 600 m.
Thanks in advance!!Please help me out! I wanna know the principel behind this so that I can solve similar questions in the future. :)
