Question

How much more fuel does the airline industry use in comparison to the motor carrier industry?

a) 2 times
b) 5 times
c) 10 times
d) 20 times

Answer 1

The airline industry uses 20 times more fuel than the motor carrier industry. If a step-up transformer is used to increase the voltage fivefold, the ratio of the number of output coils to the number of input coils should be 20 times greater.

Step-by-step explanation:

The airline industry uses 20 times more fuel than the motor carrier industry.

According to Table D.2, air freight is 100 times more energetically costly than shipping by ship. Ships are about four times more efficient per ton, carrying 5,000 times more cargo. This shows that the fuel usage of the airline industry is significantly higher compared to the motor carrier industry.

Example: If a step-up transformer is used to increase the voltage fivefold, the ratio of the number of output coils to the number of input coils should be 20 times greater.
