The result is roughly 1.19 m/s > The point is, the total time up and downstream, and therefore the average speed as well, depends on the stream speed. The same as for the supposed aether stream speed in the MMX. As the average speed along the same distance is not an arithmetic mean of one way speeds, but a harmonic mean v=2/(1/v1+1/v2). This means, with the same arithmetic mean of both speeds, their harmonic mean gets lower with growing difference of the one way speeds. -- Libor Striz aka Poutnik ( a pilgrim/wanderer/wayfarer) "Humour is the only effective weapon against stupidity."
