You are enroute to assist vessel A. Vessel A is underway at 5.5 knots on course 033°T, and bears 284°T, 43 miles from you. What is the time to intercept if you make 16 knots?

Correct Answer: Option C — 2h 32m

Solving the tactical intercept vector triangle with a 16-knot own-ship speed against a target making 5.5 knots on course 033°T from an initial bearing of 284°T at 43 miles calculates a precise intercept time of 2 hours 32 minutes.
