🔍 Key Concepts

• Use the basic speed formula: Speed = Distance ÷ Time • Convert the time interval from minutes to hours correctly • Measure the chart distance in nautical miles between the 0630 and 0654 positions

💭 Think About

• How many minutes elapse between 0630 and 0654, and what is that as a decimal of an hour? • Once you measure the distance in nautical miles on the chart, what happens to your speed if the distance is slightly more or less than 4 NM over that time? • Which answer choice best matches the speed you get when you plug your measured distance and converted time into the formula?

✅ Before You Answer

• Be sure you convert minutes → hours before dividing distance by time • Confirm your measured distance in nautical miles is along the vessel’s actual track line, not straight-line unless that is the track • After calculating, compare to choices and check for reasonable rounding (tenths of a knot)
