🔍 Key Concepts
• Fuel consumption is usually proportional to time, not distance, for a given power setting
• First, find the fuel consumption rate in tons per hour from the initial voyage data
• Use that same hourly fuel consumption rate to find how long you can steam on the remaining fuel, then convert that time to distance at 17 knots
💭 Think About
• From the initial leg, what was your steaming time in hours at 21 knots, and how many tons per hour does that work out to?
• Once you know tons per hour, how many hours can you steam on 210 tons, and at 17 knots, how many miles is that?
• After you compute the distance, which of the choices is closest to your calculated value when rounded properly?
✅ Before You Answer
• Be sure you convert miles to nautical miles correctly if needed; remember that 1 knot = 1 nautical mile per hour
• Check your units at each step: hours, knots (nm/hr), tons/hour, and miles should be consistent
• Recalculate the fuel rate to ensure it is reasonable (not an extreme value) before using it to find the final distance
