A flying cat is trying to eat a mouse. The cat is sitting on the carpet at (0, 0, -5), while a mouse is hiding up on a ledge at (2, 8, 1). What is the shortest distance from the cat’s position to the mouse’s? 

:D

If the cat can leap, then the shortest distance is the straight line between them.  Well... it would be somewhat of an arc but let's neglect that.

Yes, let's. Also, it's a FLYING cat so it goes WHEEEEEE in a straight line :D

Shortest distance  =

 

sqrt  [  (2 - 0)^2  + ( 8 - 0)^2  + ( -5 - 1)^2 ]   =

 

sqrt  [ 4  + 64  +  36 ]  =

 

sqrt [ 104 ]    =  

 

2 sqrt (26)
