This seems rather non-credible. This kind of homework problem would be along the lines of, "You have 200KM of fuel, are starting in Sacramento at the Capitol and are driving to Apple on Infinite Loop in Cupertino. Do you have enough fuel?" And supply the necessary maps, with distance scales. The "extra credit" problems would be, "Do you have enough fuel to take the tour at the Jelly Belly factory in Fairfield?" And, "Should you tour a factory that lures children into eating sugary snacks?"
OTOH, what USAF plane carries just 200KM of fuel?
