Final answer:
Trucks have better transportation efficiency compared to container ships or airplanes due to factors such as mass and speed.
Step-by-step explanation:
In terms of transportation efficiency, it is important to consider factors such as mass and speed. Container ships, for example, are difficult to push along and have lower efficiency. Airplanes also have lower efficiency due to the large distances involved in air travel, which results in substantial energy expenditure.
Table D.2 provides a summary of energy requirements for various transportation modes. It compares the efficiency in terms of kilowatt-hours per kilometer. Ships are about four times more efficient per ton compared to trucks, but trucks have a better kilowatt-hour per kilometer measure compared to ships.
Based on these factors, it can be concluded that trucks have better transportation efficiency compared to container ships or airplanes.
