You have steamed 1134 miles at 10 knots and consumed 121 tons of fuel. If you have to steam 1522 miles to complete the voyage, how many tons of fuel will be consumed while steaming at 12 knots?

Correct Answer: Option D — 234 tons

Per Bowditch standard marine engineering formulas, fuel consumption relates directly to distance and varies cubically with speed changes. Calculating $F_2 = 121 \times (1522/1134) \times (12/10)^3$ yields 234 tons required.
