Diameter ot wheel in feet X3-1416—94248, then 24X60=1440—9-4248 =152-89 revolutions of the wheel per minute provided the velocity of the wheel is the same as the water.

With an angular velocity of 0.02328 radians per second, I get a ground speed of 116 m/s (260 mph). This means the plane is moving with the same velocity (but in the opposite direction).
