I really want break this down. The have 106 miles to Chicago with a full tank of gas. The fuel tank in a 1974 Dodge Monaco 440 held 25.1 gallons (US Gallon). Itโ€™s EPA avg fuel economy (as per 1974) is 11.5mpg, but they are driving with heavy foot so Iโ€™ll give them an optimist 7mpg. That leaves them with 175.70 miles to empty.

They burned 60% of fuel in the total 106 miles traveled. I was bored.
