🔍 Key Concepts

• Use the latitude scale on the chart to measure the distance in nautical miles from your 1426 position to Chesapeake Light • Apply the speed formula: Speed = Distance / Time, and rearrange it to solve for Time • Remember that 1 knot = 1 nautical mile per hour, so keep your units consistent

💭 Think About

• After you measure the distance in nautical miles, how do you convert that distance to hours and minutes at 9.3 knots? • Once you find the elapsed time in decimal hours, how will you convert the decimal part into minutes? • When you add the travel time to 1426, what should you check to be sure your final ETA matches one of the choices?

✅ Before You Answer

• Confirm your distance measurement in nautical miles directly from the chart using the latitude scale near your position • Double-check your time calculation using $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$ with speed in knots • Make sure you correctly convert decimal hours to minutes and then accurately add to 1426 without arithmetic errors
