Determining What Current You Are Experiencing?

Your vessel is making way through the water at a speed of 12 knots. Your vessel traveled 30 nautical miles in 2 hours 15 minutes. What current are you experiencing?

Given:

Distance = 30 nautical miles
   Speed = 12 knots
      Time = 2 h 15 min or 2.25 h

What is asked?

Current you are experiencing

Solution:

1. Divide the distance by time to get the actual speed.
              30 nm ÷ 2.25 h = 13.3 knots

2. subtract 13.3 knots by the ship's speed.
              13.3 kts - 12 kts = 1.3 knots following current

It must be a following current because by our ship's speed of 12 kts steaming for 2.25 hours is expected to have traveled 27 miles. But since the problems says the ship has traveled a distance of 30 miles, so we must be experiencing a following current of 1.3 knots.
