You have steamed 836 miles at 14.5 knots, and consumed 191 tons of fuel. If you have 310 tons of usable fuel remaining, how far can you steam at 17 knots?

Correct Answer: Option D — 987 miles

Fuel consumption varies as the cube of the speed in displacement hulls (Fuel2 / Fuel1 = (Speed2 / Speed1)^3). First, calculate the hourly fuel consumption rate or apply the fuel-distance ratio with the cubic speed factor to determine that the vessel can steam 987 miles on the remaining 310 tons.
