Homework Help: Puzzles Estimation using extreme values

  1. Apr 27, 2009 #1
    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. :)
