You’re right, that would create a northern coast. That would be closer to 300M years, assuming it can continue to move at the rate of 1 CM/year, straight through Africa. Antarctica is ~4,500 KM across. The leading coast is only 1,287 KM from the South Pole, leaving 3,213 KM of land needed to migrate from the Pacific side. That would take 321,300,000 years.

same order of magnitude. also you seem to be implying the other continents are completely stationary
