393. At your current speed of 19 knots you only have enough fuel remaining to travel 265 miles. You must travel 731 miles to reach your destination. What should you reduce your speed (knots) to in order to reach your destination?

To reach the destination with the available fuel, the speed must be reduced. The required speed is calculated using the formula V2 = V1√(D1/D2), where V1 is the initial speed, D1 is the initial distance, and D2 is the required distance, resulting in a speed of 11.4 knots.
