You have steamed 264 miles and consumed 22.0 tons of fuel. If you maintain the same speed, how many tons of fuel will you consume while steaming 521 miles?

Correct Answer: Option A — 43.4 tons

Per Bowditch navigation standards, fuel consumption scales linearly with distance when engine RPM and speed remain constant. Evaluating the direct proportion (22.0 / 264) × 521 miles yields 43.4 tons of fuel required.
