🔍 Key Concepts

• Speed–time–distance relationship: ( \text{Time} = \frac{\text{Distance}}{\text{Speed}} \) and keeping all units consistent (nautical miles and knots). • Measuring distance on the chart between your 0242 position and the West Gap of Pt. Judith Harbor of Refuge, using latitude scale for nautical miles. • Converting decimal hours to minutes accurately after computing the time needed to travel.

💭 Think About

• First, determine how many nautical miles you must travel from LAT 41°16.8'N, LONG 71°39.9'W to the West Gap. What tool on the chart lets you measure this distance? • Once you know the distance and you are making 9.3 knots, how do you calculate the time in hours needed to travel that distance? Remember the correct speed–time–distance formula. • After finding the time required, how do you correctly add that time to 0242, being careful about converting decimal hours to minutes and rounding to the nearest minute?

✅ Before You Answer

• Verify that the distance was measured using the latitude scale (side of the chart) not the longitude scale along the bottom. • Check that you applied Time = Distance ÷ Speed using distance in nautical miles and speed in knots (NM/hour). • Confirm that when you convert a decimal hour to minutes, you multiply by 60 and correctly add this to 0242 without making a carry/borrowing error in minutes.
