Final answer:
The specific number of blocks Kianna walks west and south is not provided, making it impossible to answer definitively. Similar problems suggest using the Pythagorean theorem to determine straight-line distance, provided we know the distance walked in each direction.
Step-by-step explanation:
The question does not provide specific information about the number of blocks Kianna walks either west or south, making it impossible to give a precise answer.
In cases like this, it is important to analyze all given data or reach out for clarification. However, by referencing similar problems given in the prompt, we can discuss how to determine distance and displacement in a two-dimensional path if the necessary details were provided.
For example, if Kianna walked 9 blocks east and then 5 blocks south, like in one of the example problems, we could use the Pythagorean theorem to calculate the straight-line distance between the starting point and her final position.
The formula for the Pythagorean theorem is a2 + b2 = c2, where c is the straight-line distance (hypotenuse) and a and b are the distances walked east and south, respectively. Therefore, the straight-line distance can be found by taking the square root of the sum of the squares of 9 blocks and 5 blocks.
