You have steamed 803 miles at 13 knots, and consumed 179 tons of fuel. If you have 371 tons of usable fuel remaining, how far can you steam at 16 knots?
ā¢ Fuel consumption per mile vs. per hour ā¢ Proportional reasoning: using past performance to predict future range ā¢ Whether a change in speed matters when only fuel and distance are involved
ā¢ From the first part of the trip, how many tons of fuel per mile were used? ā¢ If you have 371 tons left and you keep using fuel at that same rate per mile, how many miles could you go? ā¢ Does the 16āknot speed actually change the tons-per-mile rate anywhere in the problem statement?
ā¢ First compute fuel consumption per mile from the data given (179 tons over 803 miles). ā¢ Use that rate and your remaining fuel (371 tons) to find the total possible distance. ā¢ Only after you have the distance, compare your result with the answer choices to see which one matches.
