Yeah this sort of question is asked, however with easier numbers. E.g aircraft flies 900 miles at 300 mph. Fuel 30lbs/min.
Can just work it out as 3 hours = 180 mins. 180*30 = (can do it 18x3 = 54 * 100 = 5400) and given that roughly 1lb = 0.5kg, 5400/2 = 2700Kg.
These types of question are all multiple choice, so even doing some rounding in the calculation will point to the correct answer. As I remember, the wrong answers were fairly obvious...
