From wiki - Gdańsk is 54°20′51″N 18°38′43″E, Warsaw is 52°13′56″N 21°00′30″E. Assuming the average Earth radius 6368km, Gdańsk is 3713.3km distant from Earth axis, Warsaw is 3901.5km. That gives 972.1km/h and 1021.4km/h of linear speed. The difference is 49.3km/h. Good enough for you as the first estimation, poor stinker?
