You have steamed 824 miles at 15.5 knots, and consumed 179 tons of fuel. If you have 221 tons of usable fuel remaining, how far can you steam at 18 knots?
• Fuel consumption rate in tons per mile based on the first part of the voyage • Relationship between speed, distance, and time: ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) • How fuel rate changes with speed when a new speed is given and total fuel available is known
• First, find how many tons of fuel per mile were used on the 824‑mile leg. What simple division gives you that? • Once you know tons per mile, use the 221 tons remaining to find how many miles that fuel would cover at a similar consumption rate. Which operation connects fuel on hand, fuel-per-mile, and distance? • Check whether you actually need to use the 18‑knot speed for this problem, or if the information given already lets you solve it without changing the consumption rate.
• Compute and write down the fuel consumption per mile from the first leg (tons/mile) before doing anything else. • Make sure units are consistent: miles with miles, tons with tons, not tons per hour or per day unless you convert correctly. • Before choosing an answer, quickly multiply your found miles by the tons-per-mile rate to see if it comes back close to 221 tons. If not, re-check your math.
