Your vessel arrives in port with sufficient fuel to steam 775 miles at 17 knots. If you are unable to take on bunkers, at what speed must you proceed to reach your next port, 977 miles distant?

Correct Answer: Option D — 15.1 knots

Based on the fuel-speed cubic relationship standard in marine engineering, the required speed to reach a distant port with a fixed fuel mass is computed as $17 \times \sqrt[3]{775 / 977}$, which evaluates directly to 15.1 knots.
