Difficulty: MediumInter-System Conversions

A military transport aircraft has a maximum cargo capacity of 15,000 kilograms15,000 \text{ kilograms}. The aircraft is currently loaded with 19,800 pounds19,800 \text{ pounds} of equipment. If 1 kilogram1 \text{ kilogram} is equal to 2.2 pounds2.2 \text{ pounds}, how much additional cargo, in kilograms, can the aircraft carry?

Answer: 6000 kg

Answer

6000
The remaining capacity is found by first standardizing all measurements to kilograms (19,800 pounds÷2.2=9,000 kilograms19,800 \text{ pounds} \div 2.2 = 9,000 \text{ kilograms}), and then subtracting this from the total allowance (15,000 kg−9,000 kg=6,000 kg15,000 \text{ kg} - 9,000 \text{ kg} = 6,000 \text{ kg}).

Step-by-Step Solution

1
Convert the current load from pounds to kilograms.
19,800÷2.2=9,000 kg19,800 \div 2.2 = 9,000 \text{ kg}
Since the maximum capacity is given in kilograms and the final answer must be in kilograms, the current load must be converted to the metric system.
2
Subtract the current load from the maximum cargo capacity.
15,000−9,000=6,000 kg15,000 - 9,000 = 6,000 \text{ kg}
Subtracting the weight already on board from the maximum allowable weight gives the remaining available capacity.
