Question 1 of 29218

🔍 Key Concepts

• Speed-Time-Distance relationship for ETA problems • Using the chart to measure distance along the new course line to the "abeam" position of BIS • Converting minutes of time when traveling at 18 knots

💭 Think About

• How do you find the distance from your 2027 position to the point where BIS will be abeam along a course of 106°T? Think about drawing or visualizing that leg on the chart. • Once you have that distance in nautical miles, how do you use 18 knots to figure out how many minutes it will take to travel that distance? • After calculating the travel time, how do you correctly add those minutes to 2027 to get the ETA, being careful with rounding and minute increments?

✅ Before You Answer

• Make sure the distance you use is the distance along your 106°T track to the abeam position, not straight to the buoy. • Confirm you are using the correct formula: Time = Distance ÷ Speed, with distance in nautical miles and speed in knots. • Double-check your time addition to 2027 so that your final ETA matches one of the options exactly, including the correct minute value.
