Braylon went to Los Angeles, California, for the summer to visit his cousins. He used a map of bus routes to get from the airport to his cousin’s house. The distance from the airport to his cousin’s house is 30 miles. On his map, the distance was 4 inches. What is the scale factor? Use a colon (:) to separate the ratio. e. g. 1:2 Do not use commas, e. g. 1,230 is written as 1230. Note: 1 mile = 5,280 feet.
