552. You have steamed 449 miles at 19 knots and burning 476 barrels of fuel per day. You must decrease your consumption to 185 barrels per day with 362 miles left in your voyage. What must you reduce your speed (kts) to in order to burn this amount of fuel?

To meet the fuel consumption limit, the remaining distance must be traveled at a speed determined by the cube law relationship between fuel consumption and speed, resulting in a required speed of approximately 13.3 knots, making 13.2 knots the closest and correct answer.
