You are enroute to assist vessel A. Vessel A is underway at 4.5 knots on course 233°T, and bears 264°T at 68 miles from you. What is the course to steer and running time at 13 knots to intercept vessel A?

Correct Answer: Option C — 254°, 7h 37m

Executing a vector triangle solution for target interception using a 13-knot own ship speed against vessel A running at 4.5 knots on course 233°T from a bearing of 264°T at 68 miles results in course 254°T and 7 hours 37 minutes running time.
