Tracy, John and Jake found their combined weight to be 158 kilograms. If Tracy weighs 52 kg and Jake weighs 8kg more than Tracy, what is the range of their weights? Let's think first. Chain of thought:
Jake weighs 8kg more than 52 kg which is 8 + 52 = 60 kg. Tracy and Jake together weigh 60 + 52 = 112kg. John therefore weighs 158 - 112 = 46 kg. The range of their weights is 60 - 46 = 14kg.
Therefore, the answer is 14.
