264. 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?

The problem requires determining a new speed to reduce fuel consumption. Without a specified relationship between fuel consumption and speed, a unique solution cannot be derived, and the provided answer of 15.1 knots should be verified against the original exam materials.
