Question

Transcribed image text: Suppose that you want to arrange a meeting with two other people at a secret location in Manhattan that is an intersection of two streets (let's say 110th street and 2nd avenue, for concreteness). You want to send each of them a message such that they can find the location if they work together, but neither one can find it on their own. What could you send to each of them? Explain your reasoning.

Answer 1

You could send each person one half of the coordinates of the secret location, such as "110th street" to one person and "2nd avenue" to the other person. This way, they would need to work together to share their information and determine the exact location of the intersection.

This approach ensures that neither person can find the location on their own, as they only have half of the information needed to determine the intersection. Additionally, sharing the coordinates separately adds an extra layer of security to the meeting location as it would be difficult for anyone to determine the meeting location without both pieces of information.

However, it's important to ensure that each person understands the instructions clearly, so they know to work together to determine the secret location. It's also important to choose a location that is not well-known, so the possibility of someone stumbling upon the meeting location by chance is reduced.
