413. You have steamed 775 miles at 17 knots, and consumed 145 tons of fuel. If you have to steam 977 miles to complete the voyage, how many tons of fuel will be consumed while steaming at 18 knots?
Fuel consumption for a displacement vessel is proportional to the cube of the speed. Therefore, the remaining 977 miles at 18 knots will consume approximately 204 tons of fuel.
