One of Madison's hobbies is to locate hidden geocaches. To find yesterday's cache, Madison was instructed to start at a water fountain at a local park. Then, the directions had her walk 15 yards due west and 8 yards due south. If this was the location of the cache, how far was it from the water fountain where she started?

B.
23 yards
C.
12 yards
D.
7 yards

Good grief, that is simple Pythagoras !
How could the bot miss this one ???

d^2 = 15^2 + 8^2 = 289
d = √289
= 17

The bot does not know what it is doing. It is very frustrating.
