🔍 Key Concepts

• Time-Speed-Distance relationship: ( \text{Time} = \frac{\text{Distance}}{\text{Speed}} \) • Using the chart to measure the distance between your 0919 position and the line between Buoys "17" and "18" • Converting hours and decimal hours into hours and minutes for ETA

💭 Think About

• First, on the chart, how will you find the distance from your 0919 position in the channel to the line between Buoys "17" and "18"? • Once you know the distance, how do you use 11.3 knots to find the time in hours, and then convert that to minutes? • After you compute the running time, how do you correctly add it to 0919 to get a realistic arrival time among the options given?

✅ Before You Answer

• Be sure your distance measurement is in nautical miles, not yards or statute miles • Check that your time calculation uses 11.3 knots as nautical miles per hour • When adding time to 0919, watch for minute carry-over (e.g., if minutes exceed 60) so your final ETA is a valid clock time
