🔍 Key Concepts

• Fuel consumption per mile based on the first leg of the voyage • How speed in knots relates to time taken to travel a fixed distance • Using proportions to scale fuel use from one distance/speed to another

💭 Think About

• First, find how many tons of fuel per mile were used on the 1175-mile leg. What simple division will give you that? • Next, for the remaining 1341 miles, how can you adjust for the fact that you will be traveling at a different speed (18 knots instead of 19 knots)? Should fuel use depend mainly on distance, time, or both in this type of exam problem? • Once you decide what stays the same between the two legs (e.g., fuel per mile or fuel per hour), set up a proportion to find the unknown fuel consumption for the second leg.

✅ Before You Answer

• Carefully compute fuel per mile for the first leg and write it down to enough decimal places to avoid rounding error. • Decide explicitly whether you are assuming fuel per mile or fuel per hour is constant between 19 knots and 18 knots; this choice determines your next formula. • After calculating the fuel for the second leg, compare your result with the multiple-choice options and check if any rounding you did reasonably leads to one of them.
