Question 1 of 2707066636eea28f7522a1c51a818

At 0430, you change course and speed to make good 090°T at 10 knots. At 0433, you slow due to an engineering casualty and estimate you are making good 5.5 knots. At what time will Branford Reef Light bear 000°T?

Question 1 of 27070

🔍 Key Concepts

• Course made good vs. speed through the water after a change in speed • Using time-speed-distance: Distance = Speed × Time, remembering to convert minutes to hours • How to determine when a fixed object is on a given bearing from your track line on the chart

💭 Think About

• From 0430 to 0433, how far did you travel at 10 knots, and how far have you gone along the track by 0433? • Once you slow to 5.5 knots at 0433, how long will it take to reach the point on your track where Branford Reef Light bears 000°T? • Which answer choice matches the total elapsed time from 0430 to when you are abeam (bearing 000°T) of Branford Reef Light?

✅ Before You Answer

• Be sure you convert minutes to hours correctly when using knots (nm/hr) in the time-speed-distance formula. • Confirm you are measuring the distance along your course line from your 0430 position to the abeam point of Branford Reef Light, not straight to the light. • Double-check your intermediate time at 0433 and then add the additional time at 5.5 knots to get a final clock time.
