Assuming no current, at what time can you...

🔍 Key Concepts

• Speed–Time–Distance relationship:

\text{Time} = \frac{\text{Distance}}{\text{Speed}}

• What "abeam" means in piloting (bearing about 090°/270° relative, i.e., roughly off your beam) • Effect of "no current" on your speed over ground (SOG) vs. speed through the water

💭 Think About

• From earlier in the problem, determine the vessel’s speed and the distance from your last known time/fix to the point where you will be abeam of Townshend Ledge Lighted Buoy. • Use the speed–time–distance formula to find how many minutes it takes to travel that distance, then add that to your starting time to get the expected abeam time. • Think about what "no current" allows you to ignore in your calculation and how that simplifies your ETA.

✅ Before You Answer

• Be sure you are using nautical miles for distance and knots for speed so the units match. • Verify exactly from which time/fix the question wants you to measure the run to the abeam position. • Confirm on the chart where the vessel is when the buoy will be abeam (on the beam, not ahead or abaft the beam) before computing the time.

Assuming no current, at what time can you expect to be abeam of Townshend Ledge Lighted Buoy?
