🔍 Key Concepts

• Relationship between speed and fuel consumption for displacement vessels (often approximated by a cube law: fuel ∝ speed³) • How to use ratios when you know fuel consumption at one speed and need it at another speed • Careful calculator work: doing the speed ratio first, then applying the power (square or cube)

💭 Think About

• If fuel burn at 14 knots is known, how can you express the new fuel burn at 11.7 knots as a multiple or fraction of the original burn? • Should the fuel consumption go up or down when you slow from 14 to 11.7 knots? By a lot or by a little? Estimate first, then calculate. • What mathematical operation do you apply to the speed ratio (new speed / old speed) before multiplying it by 276 bbls/day?

✅ Before You Answer

• Compute the speed ratio correctly: 11.7 ÷ 14 (not the other way around). • Apply the correct exponent to the speed ratio before multiplying by 276 bbls/day. • After calculating, check whether your result is less than 276 (it must be, since you reduced speed) and reasonably close to one of the options.
