You have steamed 142 miles and consumed 21.0 tons of fuel. If you maintain the same speed, how many tons of fuel will you consume while steaming 465 miles?

Correct Answer: Option C — 68.8 tons

Applying direct proportionality rules from Bowditch for constant-speed steaming, the ratio of fuel to distance remains fixed. Solving the expression (21.0 / 142) × 465 miles yields a total fuel consumption of 68.8 tons.
