You have steamed 989 miles at 16.5 knots, and consumed 215 tons of fuel. If you have 345 tons of usable fuel remaining, how far can you steam at 13 knots?

Correct Answer: Option D — 2557 miles

Calculate baseline fuel consumption per mile, then apply the cubic speed law to the remaining 345 tons of fuel at 13 knots, resulting in a maximum distance of 2557 miles.
