70% to pass

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?

A 274°, 7h 37m
B 254°, 7h 37m
C 254°, 8h 35m
D 274°, 8h 35m
AI Explanation

The correct answer is B) 254°, 7h 37m. To determine the correct course and running time, we need to use basic navigation principles. Given that Vessel A is at 264°T and 68 miles from your position, we can calculate the course to steer to intercept Vessel A. Using the trigonometric formula, the course to steer is 254°T. Additionally, the running time to intercept Vessel A at 13 knots is 7 hours and 37 minutes. The other options are incorrect because they either have the wrong course (274°) or the wrong running time (8 hours and 35 minutes). The correct course and running time are 254° and 7 hours and 37 minutes, respectively, based on the information provided.
