Thomas 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 56 km. On his map, the distance is 4 cm. What is the scale factor?
14 , 56 km = 56 × 100000 = 5600000 cm 5600000 ÷ 4 = 1400000 4 ÷ 4 = 1 5600000:4 ratio simplified is 1400000:1 so if you take all the zeros off , it will be exact 14 .
