You have steamed 156 miles and consumed 19 tons of fuel. If you maintain the same speed, how many tons of fuel will you consume while steaming 273 miles?

Correct Answer: Option C — 33.3 tons

Fuel consumption varies directly with distance assuming constant speed and rate. Setting up a direct proportion ($\frac{19\text{ tons}}{156\text{ miles}} = \frac{x}{273\text{ miles}}$) and solving algebraically yields $33.3$ tons consumed.
