A concrete road surface consists of 15-m long sections separated by gaps to allow for thermal expansion as the weather changes. suppose the expected road surface temperatures vary during the year from a low of -15 degrees Celsius to a high of 45 degrees Celsius. (Note: On a sunny day, road surface temperatures can be much higher than air temperatures.) The road is designed so that there remains a 2.0 mm gap between sections on the hottest day. What is the gap on the coldest day?
