If a sailboat leaves Miami at 5 knots per hour, how fast will it
be going when it reaches Panama?

Impossible to determine without knowing its starting speed.

Starting speed: 0 Knots.

Can you give an instance when this is _not_ the case? Every time
I've started a trip I've experienced a starting speed of roughly
zero knots. give or take.

When you have to back out of the slip! -0.25 knots!

What was the vessel's velocity relative to the geodesic coordinate frame
when it _began_ moving in reverse?


OK, I'm stumped. Isn't the geodesic coordinate frame that house designed by
buckminster fuller in the 60's or 70's?
