🔍 Key Concepts

• Relationship between speed and fuel consumption for displacement vessels (approximately proportional to the cube of the speed) • Setting up a ratio or proportion between fuel burn at two different speeds • Using exponents (speed³) to compare power or fuel requirements

💭 Think About

• How does required power (and thus fuel burn) typically change when a ship’s speed changes slightly—linearly, with the square, or with the cube of speed? • Can you set up a ratio using the two speeds to compare fuel consumption per hour without first finding total fuel? • Once you compute the new fuel consumption, which answer choice is closest to your calculated value?

✅ Before You Answer

• Be sure you convert both speeds using the same units (knots to knots is already consistent). • Double-check your use of the exponent on speed (are you cubing the correct values?). • After calculating, confirm the result is less than 6 tons per hour but still reasonable for a small reduction in speed.
