To calculate the fuel efficiency (E):
\[ E = \frac{TM}{TG} \]
Where:
Fuel efficiency is defined as the total miles per gallon of fuel that a car can travel. It is used to describe how efficiently a car takes fuel and converts it into movement. Higher fuel efficiency means that a car can travel more miles per gallon of fuel, which is beneficial for cost savings and reducing environmental impact.
Let's assume the following values:
Using the formula:
\[ E = \frac{300}{15} = 20 \text{ miles per gallon (mpg)} \]
The fuel efficiency is 20 miles per gallon (mpg).
