You have steamed 369 miles at 16 knots and burning 326 barrels of fuel per day. You must decrease your consumption to 212 barrels per day with 271 miles left in your voyage. What must you reduce your speed (kts) to in order to burn this amount of fuel?

🔍 Key Concepts

• Relationship between speed, time, and distance: ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) • How fuel consumption per day changes with speed (is it linear for this exam-type problem?) • Using the same fuel-per-mile ratio to project a new speed that matches the required daily fuel consumption

💭 Think About

• First, find how many hours or days it took to run the first 369 miles at 16 knots, then relate that to the 326 barrels per day to get fuel per hour or fuel per mile. • Use that fuel-per-hour or fuel-per-mile figure to determine what fuel rate per hour corresponds to 212 barrels per day, and then find what speed produces that rate over the remaining miles. • Compare the resulting speed with the answer choices and think about whether the speed should be noticeably higher or lower than 16 knots if you want to reduce fuel consumption.

✅ Before You Answer

• Be sure to convert knots to hours correctly: 1 knot = 1 nautical mile per hour. • Confirm you are using consistent time units (all in hours or all in days) when relating speed and fuel consumption. • Verify that your final speed is less than 16 knots, since you are trying to reduce fuel consumption, and check which of the choices make sense with your calculations.
