Air transport is the fastest mode of transport.

Answer:

• Aeroplanes travel at very high speed and take a direct route through the air, so long distances are covered in a few hours, which would take days by road, rail or sea.
• Air transport is not obstructed by mountains, forests, rivers, deserts or seas.
• It is best suited for urgent and perishable goods like medicines, flowers, fruits, mail and costly articles of small weight.
• It is very useful during emergencies such as floods, earthquakes and wars, for quick relief and rescue.
• It connects distant and difficult areas, and countries across the world, quickly.

Hence, air transport is the fastest mode of transport, though it is costly and has limited carrying capacity.
