🔍 Key Concepts

• Using the chart to measure total distance between two points • Converting minutes of latitude to nautical miles • Accounting for the fact you are not exactly at Bridgeport but about 7 miles away

💭 Think About

• How would you measure the distance from Bridgeport, CT, to Newport, RI, on the chart, and then adjust it because your position is not exactly at Bridgeport? • Are you using the latitude scale (on the side of the chart) to measure nautical miles, and lining up your dividers correctly? • Once you find the distance on the chart, does your final answer seem reasonable for a run between those two ports?

✅ Before You Answer

• Verify that you are measuring along the correct track line between your 0507 position and Newport, RI • Confirm that the distance from 1 minute of latitude = 1 nautical mile is correctly applied • Double-check whether you must add or subtract the 7 miles from Bridgeport based on where your 0507 position lies relative to the port and your route to Newport
