take difference of plane weights and divide by difference in number of gallons of fuel on board to get weight of fuel per gallon.  Now subtract target number of gallons from number of gallons used in one of the weight measurements to find number of additional gallons needed, multiply by weight per gallon found, and add to the weight of the plane.

anonymous · Answer

first find the weight of each gallon of fuel 
thus each gallon weighs = (2241-2024)/(55-20) =217/35 =6.2

anonymous · Answer

hence for additional 65-55=10 gallons it will weigh 62 more
