-----
knots is a unit of speed, = 1 nm/hour
--> knots/hr is acceleration, tho not a commonly used unit
---------------------
At the end of 4 hours, the boat's speed is 4*5.5 = 22 knots.
The average speed is (0+22)/2 = 11 knots
4*11 = 44 nautical miles.
=============================
Never seen "knots/hour" used before.

Flying in Vietnam, we had airspeed in knots, maps in kilometers, altimeters in feet.
Vertical speed indicators (VSI) in feet/minute.
And people shooting at us.

From a dictionary, learn the meaning of the term "knot" and use it   P R O P E R L Y.

In this context, a knot is one nautical mile per hour. It is the unit of speed - not the unit of distance.
