🔍 Key Concepts

• Fuel consumption is usually based on tons of fuel per mile, not per hour • When speed changes, the distance you can travel with the same fuel depends on your fuel per mile, not directly on knots • Use the proportion: if X tons lets you go 632 miles, how many miles for 278 tons at the same consumption rate?

💭 Think About

• First, find how many tons of fuel per mile you used on the 632-mile run • Next, assume the same consumption per mile for the remaining fuel unless told otherwise—how many miles will 278 tons give you? • Finally, check whether the change in speed from 18.5 to 15.0 knots actually affects fuel per mile in this question or is just extra information

✅ Before You Answer

• Be sure you divide fuel by miles, not fuel by hours, for the initial leg • Confirm that your fuel per mile number makes sense (it should be a small fraction of a ton per mile) • After finding the distance, compare with choices and ask: does any option require using the 15.0 knots value in a way that conflicts with constant fuel-per-mile consumption?
