one international mile is defined as exactly 607601155 ft, 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 14.3 knot?

Answer 1

You left out a decimal point in your definition of an international (nautical) mile. It is 6076.011.. feet. Let's just write it as 6076 feet since you have only three significant figures in the 14.3 knots.

14.3 NM/h * 6076 ft/NM * 0.3048 m/ft * 1 h/3600 s = ______ m/s

Multiply the numbers as shown and the dimensions will turn out to be m/s.
