308. You have steamed 1587 miles at 11.2 knots, and have consumed one-half of your total fuel capacity of 2840 bbls. What is the maximum speed you can steam to complete the remaining 1951 miles?

Fuel consumption is proportional to the square of speed and distance. With half the fuel remaining and a longer distance to cover, the speed must be reduced to approximately 10.1 knots to ensure sufficient fuel for the remaining journey.
