Older rаilrоаd trаcks in the U.S. are made оf 15 m lоng pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16°C, by how much could one piece of track expand if the temperature gets as high as 42°C? Show your work or explain your reasoning.
