The United States Geological Survey (USGS) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States and prepare detailed maps of every portion of the United States at a scale of 1:24,000. James has a USGS map of the rural neighborhood where he lives and measures that his school is a straight line distance of 15 inches from his home. Rounding to the nearest tenth of a mile, how many miles is his school from his home in a straight line? (Recall that there are 5280 feet in a mile and 12 inches in a foot.)
