You are enroute to assist vessel A. Vessel A is underway at 5.5 knots on course 033°T, and bears 248°T at 64 miles from you. What is the time to intercept if you make 13 knots?
AI Explanation
The correct answer is D) 3h 44m.
To determine the time to intercept, we need to calculate the distance to the vessel and the relative speed between the two vessels. Given that vessel A is bearing 248°T at 64 miles, and you are making 13 knots, we can use the formula: Time to intercept = Distance / Relative Speed.
The relative speed is the difference between your speed (13 knots) and the speed of vessel A (5.5 knots), which is 7.5 knots. The distance to vessel A is 64 miles. Plugging these values into the formula, we get: Time to intercept = 64 miles / 7.5 knots = 3h 44m.
The other options are incorrect because they do not accurately calculate the time to intercept based on the given information.
