Your vessel has consumed 1087 bbls of fuel after steaming 2210 miles at a speed of 10.75 kts. What is the maximum speed you can steam for the last 1000 miles of the voyage on the remaining 725 bbls, if you estimate 3% of the fuel is not usable?

Correct Answer: Option C — 12.84 knots

Subtracting the 3% unpumpable reserve from 725 total barrels leaves 703.25 usable barrels. Applying Bowditch fuel consumption and distance formulas ($Fuel = Rate \times Time$) across the remaining 1000 miles determines the maximum allowable steaming speed is 12.84 knots.
