How do you understand the speed of a boat in standing water? and got a better answer
Response from Дима[+++]
in standing water - that is without taking into account the current, that is, if the boat or boat is floating on the lake do you know how a speedometer device for measuring speed works? probably there is a calculation based on the number of revolutions of some propeller in the water So the speed on the speedometer for two boats on the lake and swimming against the current may be the same, but in fact the first boat will come faster?

Probably from the speed of the current. Or the water is standing, like in the lake.

Elementary. Motorized propulsion gives you more speed than hand paddling the fucker.

That's assuming there's no current. If there is a current then boat speed upstream= boat speed + current speed and against the current:= boat speed - current speed

this means that the water has no current velocity

if in a river you would have to consider the speed of the current and whether upstream or downstream but here the condition only has the speed of the vehicle

so it is the boat's own speed the water has no effect on the speed

if the river had current - you would have to either add or subtract the speed of the current
