Question 1159874
A boat leaves the dock and travels at 5.5 knots per hour headed East.
How far does it go in 4 hours?
-----
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.
