Question

One international nautical mile is defined as exactly 6076.1155ft and a speed of 1 knot is defined as one international nautical mile per hour. What is the speed in meters per second of a boat traveling at a speed of 14 knots?

Answer 1

$1 ~international ~nautical ~mile =~ 6076.1155~ ft =~1852~meter =~1.852 ~km$

$1 ~knot =~ 1 ~international ~nautical ~mile/hour=~1.852 ~km/hour$

$14~knot = ~14*~ 1.852 =~ 25.928 ~km/hour$

$1~km/hour = 0.27778 ~meter/sec$

$25.928~km/hour =~ 25.928 *~ 0.27778 =~\bold{ 7.2 meter/sec}$

Answer: 7.2 meter/sec
