It is about 2244.5 nautical miles from Los Angeles, CA to Honolulu, HI. A boat starts from being at rest in Los Angeles Harbor and proceeds at 1 knot per hour to Honolulu. How long does it take?
1 Knot = 1 nautical mile per hour, a speed measure, so 1 Knot per hour
is an acceleration measure. Starting at zero speed and A acceleration,
after T time you travel ½AT²; equating this with 2244.5 gives T=67.
This
solution has a slight problem: the boat will be moving at AT speed (=67
nautical miles per hour, about 75 miles/hour or 120 kilometers/hour)
and it may be hard to stop!
