**- GOING FURTHER -
Yet another characteristic quantity for automobiles comes from the fact
burning a gallon of gasoline produces about 20 lbs. of carbon dioxide.
[How can that be?]
Consider now the following five characteristic quantities
- average speed in mi/hr
- average fuel efficiency in mi/gal
- average fuel cost in $/gal
- average weight of fuel (specific gravity) in lb/gal
- average weight of carbon dioxide produced per gallon of fuel burned in lb/gal
How many additional distinct characteristic intensive quantities can you formulate?
What are they? What are their values?
To what question(s) is each of these additional quantities a potential answer?**
