210. 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?

Fuel consumption is directly proportional to distance at a constant speed. Therefore, fuel consumption for 273 miles is calculated by multiplying the initial fuel consumption (19 tons for 156 miles) by the ratio of the new distance to the original distance (273/156), resulting in 33.3 tons.
