"Mileage" is a term which, by convention, is used to refer to how far your internal-combustion-engine-powered vehicle can travel per gallon of fuel. So, the mileage from Lodi, CA to Merced, CA would depend on what vehicle you are driving to travel between the two cities.
Also, your question uses the term "toMerced". toMerced would be a great name for a variable in a C++ program, but in the question you should separate the preposition from its object with a single space. Thus, your question should be: What is the mileage from Lodi, CA to Merced, CA?
