Question 1003Navigation General

The correct answer is D) 7h 37m. To calculate the time to intercept, we need to find the distance between the two vessels and the relative speed between them. The distance between the vessels is 68 miles, and the relative speed is the difference between your speed (13 knots) and the other vessel's speed (4.5 knots), which is 8.5 knots. Using the formula: Time (in hours) = Distance (in nautical miles) / Relative Speed (in knots), we get 68 miles / 8.5 knots = 7.37 hours, or 7h 37m. The other options are incorrect because they do not accurately calculate the time to intercept based on the given information.
