You have steamed 1124 miles at 21 knots, and consumed 326 tons of fuel. If you have 210 tons of usable fuel remaining, how far can you steam at 17 knots?

Correct Answer: Option B — 1105 miles

Fuel consumption varies with the cube of the speed. Calculate the fuel rate at 21 knots, adjust for the new speed of 17 knots using the cubic relationship, and determine the remaining range. With 210 tons remaining at 17 knots, the vessel can steam 1105 miles.
