A knot is a measurement of speed, equivalent to one nautical mile per hour. It's nonsensical to propose to measure distance in knots. One properly measures distance in nautical miles, in cases where that's the appropriate measure. (Other cases might want kilometers, for example.)
"Knots per hour" is not a measurement of speed. It can technically (but not practically) be used as a measurement of acceleration, but that's not relevant.
Maybe you shouldn't pretend you know what you're talking about when it comes to shipping.
Of course you can calculate apx distance travelled if you have the parameters of unit of speed x time taken.
For example, a car travelling at 60mph for 20 mins can be estimated to have traveled 20 miles (60 x 0.33333).
