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?

Correct Answer: Option C — 204 tons

Calculate the fuel consumption rate per mile at 17 knots. Adjust this rate for 18 knots using the cubic law (F2 = F1 * (V2/V1)^3). Multiply the new fuel-per-mile rate by the remaining distance of 977 miles to determine the total fuel required for the remainder of the voyage.
