Q

If your vessel burns 2.9 tons of fuel per hour operating at a speed of 20 knots, how many tons per hour will it burn at a speed of 15 knots?

🔍 Key Concepts

• Fuel consumption vs. speed (how fuel use changes when speed changes) • Relationship between speed and time per mile • How to use ratios or proportions when one variable changes and another depends on it

💭 Think About

• How many nautical miles per hour is the vessel traveling at 20 knots compared to 15 knots? • If it takes more time to travel one mile at a lower speed, how does that affect the fuel burned per hour, assuming the fuel burned per mile stays the same? • Can you set up a proportion using fuel per hour and speed to find the new fuel rate at 15 knots?

✅ Before You Answer

• Compute fuel burned per nautical mile at 20 knots before changing speeds • Use a proportion that keeps fuel per mile constant when changing from 20 to 15 knots • Double-check units: make sure you are comparing tons per hour to knots (nautical miles per hour) consistently
