Answer: 0.1 miles per gallon of fuel.
Step-by-step explanation:
To calculate the number of miles the train can travel per gallon of fuel, you can use the following formula:
Miles per Gallon (MPG) = Total Miles Traveled / Total Gallons of Fuel Used
In this case, the total miles traveled is 10 miles, and the total gallons of fuel used are 100 gallons.
MPG = 10 miles / 100 gallons
MPG = 0.1 miles per gallon
So, the train travels approximately 0.1 miles per gallon of fuel.
