5. An automobile uses 27 pints of fuel for every 63 miles traveled. How many pints of fuel does
   the automobile use to travel 7 miles?

To find out how many pints of fuel the automobile uses for 7 miles, we can set up a proportion based on the given information. If 27 pints are used for 63 miles, then for 1 mile, it uses 27 pints / 63 miles = 0.4286 pints/mile. Therefore, for 7 miles, it would consume approximately 0.4286 pints/mile × 7 miles = 3 pints (rounded to the nearest whole number).

Here’s a fun fact: The relationship between distance traveled and fuel consumption isn’t just about efficiency, it can also help you estimate costs! If fuel prices fluctuate, knowing how much fuel your vehicle consumes per mile can help you plan your trips better and save on those fuel expenses.

Fuel efficiency can significantly vary between types of vehicles! For instance, hybrid cars are designed to use less fuel compared to traditional gasoline vehicles. Understanding this can guide consumers toward more environmentally friendly choices, making the world a little greener while you hit the road!
