426. While steaming at 14.5 knots, your vessel consumes 242 barrels of fuel oil per day. In order to reduce consumption to 152 barrels of fuel oil per day, what is the maximum speed the vessel can turn for?
Fuel consumption is proportional to the cube of speed; therefore, to reduce fuel consumption from 242 to 152 barrels per day, the maximum speed is 12.4 knots.
