George v coast in Antarctica is the windiest place on earth. Wind speeds there can reach 3.00 x 10^{2} km/h. if a research plane flies against the wind with a speed of 4.5 x 10^{2} km/h relative to the wind, how long does it take the plane to fly between two research stations that are 250 km apart?
