The correct answer is: Traveling by air is faster than traveling by sea.

Airplanes can travel much faster than ships. The average speed of a commercial airliner is about 500 miles per hour, while the average speed of a cruise ship is about 20 miles per hour. This means that it takes about 2.5

In addition, airplanes are not affected by the weather as much as ships are. This means that airplanes can usually fly on time, even in bad weather. Ships, on the other hand, can be delayed or even cancelled due to bad weather.

Finally, airplanes are more comfortable than ships. Airplanes have seats that recline, and they have in-flight entertainment systems. Ships, on the other hand, have more limited space, and they may not have in-flight entertainment systems.

For all of these reasons, traveling by air is faster and more convenient than traveling by sea.
