If you are making 8.3 knots over the ground, what is your ETA at the turning point in York Spit Channel at buoy "29"?
• Use the basic speed–distance–time relationship: Time = Distance ÷ Speed • Convert decimal hours into minutes carefully (watch place value) • Add the running time to the departure time given earlier in the problem/worksheet to find ETA
• From your chart work or earlier steps, what is the total distance (in nautical miles) from your present position to buoy 29? • Once you compute time in hours, how do you correctly change the decimal part of an hour into minutes? (e.g., 0.2 hr is NOT 2 minutes) • After you get the running time, how do you properly add it to the initial time to get a four‑digit 24‑hour ETA?
• Be sure your distance is in nautical miles, not yards or statute miles • Double‑check your conversion from decimal hours to minutes (multiply the decimal by 60) • Verify that your final ETA makes sense: does the time difference between now and ETA match the running time you calculated?
