Question 1002Navigation General
70% to passYou are enroute to assist vessel A. Vessel A is underway at 6 knots on course 133°T, and bears 343°T at 92 miles from you. What is the time to intercept if you make 9 knots?
A
7h 12m
B
7h 44m
C
6h 08m
D
6h 43m
AI Explanation
The correct answer is D) 6h 43m. To calculate the time to intercept, we need to use the relative motion formula: Time = Distance / (Your Speed - Target Speed). Given: - Vessel A's speed: 6 knots - Your speed: 9 knots - Distance to Vessel A: 92 miles Plugging these values into the formula: Time = 92 miles / (9 knots - 6 knots) = 92 miles / 3 knots = 6h 43m The other answer choices are incorrect because they do not correctly apply the relative motion formula to calculate the time to intercept.
