🔍 Key Concepts

• Relationship between distance traveled and fuel consumed at a constant speed and operating condition • How to find fuel consumption per mile and then scale it to a new distance • Checking your math with proportions to see if the answer is reasonable

💭 Think About

• First, how many tons of fuel are used per mile based on the initial data? • Once you know tons per mile, how can you use that rate to find fuel used for 285 miles? • After calculating, does your result seem larger or smaller than the original 14.0 tons, and is that reasonable for the increased distance?

✅ Before You Answer

• Carefully divide fuel used by miles steamed to get tons per mile (watch your calculator and decimal places). • Multiply that tons-per-mile rate by 285 miles and write down the exact result before rounding. • Compare your final number to the answer choices and to the original 14.0 tons to see if it is logically consistent (more miles should mean more fuel).
