You are enroute to assist vessel A. Vessel A is underway at 5 knots on course 063°T, and bears 136°T at 78 miles from you. What is the course to steer and running time at 13 knots to intercept vessel A?

A 158°, 7h 20m
B 115°, 5h 45m
C 158°, 5h 45m
D 115°, 7h 20m
AI Explanation

The correct answer is D) 115°, 7h 20m. To intercept vessel A, you need to calculate the course to steer and the running time to reach vessel A's position. The key information given is the bearing and distance of vessel A from your position. Using the bearing and distance, you can calculate the course to steer and the running time. The course to steer is 115°, and the running time at 13 knots is 7 hours and 20 minutes. The other options are incorrect because they do not correctly calculate the course to steer and running time based on the provided information.
