I've gotten lots of ideas that use just the P theorem, (what i mean, is where you already know the length of two sides and want to find the diaganol, for example)... but none that fit the assignment which is:

"The distance formula needs to be applied to at least two real-life examples, which means coordinate axes need to be defined and coordinates need to be assigned to the points." (in 3d)

I appreciate any direction that can be provided.
