Speed of behemoth sub base on earth ground is right with 0 km/h = 0 knts

Speed base on earth rotaion is 
U = D x pi with D = 12730 km and pi = 3,1415 
U = 39992 km at one day of 24 hours
so speed is 39992/24 = 1666 km/ hour or about 900 knots around the earth
centerpoint. 

Based on rotating earth around the sun is 
about 29,78 km/sec or 107208 km/hour or 57888 knots.. not calculating
the earth rotation. 

So which one os right for the sub = O , 900 or 57888 knots.. ? 

So most psubs run around 57900 knots + - a figure tolerance of 0,01 % 
around the sun and it doesn't matter if the propeller spins or not. ;-)
