Thanks..... that made my morning.

Even if you assume a decimal point off.... still funny

I wonder if some student refused to answer the question because the speeds for the sailboat were not given in knots.

Knots are a non-SI unit of measure (meaning non-metric). Mathematicians, and physicists hate that.

Everyone knows that km=thousand millimeters.:liar:

The real answer is ZERO!

If they were both towing the same dinghy, maybe there would be a dinghy RESULTANT VELOCITY on Jupiter.

Ya'll are GPS brain dead!

If a train left Chicago at 3 AM making 10 furlongs per fortnight and another left Key West at 4 AM, making 16 knots, where would they meet ? What time in the Lunar Cycle would it be when they met?

Real boating question...

If a crooked lawyer fell over board and you were going to toss him a Life Sling. You toss your life sling at a component windward speed of 4 knots/hour in a SSW direction and a component 1.2 knots/hour True North, would the resultant life sling vector reach the drowning lawyer?

The theoretical answer is 206.16, however the boat would have lost its rig and probably all hands well before reaching that speed. Even if he had a couple of 502 Chevy V8s, and a reasonable planing hull, the 50 knot winds would be a problem.

Try to figure out what the waterline length on displacement hull would have to be to reach that speed. Assume no friction and no wind resistance.

Actually, none of the choices is correct. Velocity is a vector and, therefore, includes speed and direction. The correct answer is 206.16 km/h at a heading of 284 degrees.

those Knots would fall in the same catagorie as fathoms and leagues all of witch i assume are nautical terms
