317. You have steamed 463 miles at 19 knots and burning 440 barrels of fuel per day. You must decrease your consumption to 200 barrels per day with 410 miles left in your voyage. What must you reduce your speed (kts) to in order to burn this amount of fuel?

Fuel consumption is proportional to distance times the square of speed. To reduce fuel consumption to a specified amount, calculate the required speed using the proportional relationship between fuel, distance, and speed squared, resulting in a speed of approximately 13.6 knots.
