At your current speed of 19 knots you only have enough fuel remaining to travel 265 miles. You must travel 731 miles to reach your destination. What should you reduce your speed (knots) to in order to reach your destination?

Correct Answer: Option D — 11.4

Fuel consumption follows the cubic law: consumption is proportional to the cube of the speed. To cover 731 miles with limited fuel, calculate the new speed using the ratio of distances and the cubic relationship. Reducing speed to 11.4 knots ensures the vessel reaches the destination within fuel constraints.
