Question: how many hours does it take to fly over the atlantic ocean?
Answer: Typical speed of airliners is between 500 to 550 mph (the most economic speed), so basically 7.3 to 8 hours. If you are asking about some other distance, just get the distance and use 550 mph to calculate the time. However, a tail or head wind can increase or reduce a plan's speed by up to 100 mph.
