Q

Your vessel is making way through the water at a speed of 12 knots. Your vessel traveled 30 nautical miles in 2 hours 20 minutes. What current are you experiencing?

🔍 Key Concepts

• Speed = Distance / Time for both vessel speed through the water and speed made good over the ground • Difference between speed through the water and speed over the ground tells you the current • Direction of current: head current slows you down; following current speeds you up

💭 Think About

• First, convert 2 hours 20 minutes fully into hours and find your actual speed over the ground from 30 nautical miles traveled. • Compare your speed over the ground to your known speed through the water (12 knots). Is the vessel being helped or hindered? • The size of the difference between the two speeds gives the drift of the current. How many knots is that difference?

✅ Before You Answer

• Be sure you convert 20 minutes to hours correctly before calculating speed. • Confirm whether your speed over the ground is greater or less than 12 knots to decide between head or following current. • Double-check that the numerical drift you calculate (in knots) matches one of the given choices before picking your answer.
