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

Correct Answer: Option D — 7h 37m

Executing the vector solution for intercepting a moving vessel with an own-ship speed of 13 knots requires constructing a relative motion triangle based on initial range and bearing, resulting in a precise running time of 7 hours 37 minutes.
