Amap has a scale of 1 cm : 15.5 km. two cities are 2.3 cm apart on the map. to the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?
38 km
51.2 km
35.7 km
113.2 km

You will need to multiply 15.5 by 2.3. Keep in mind that this only works because the scale is 1cm but if it was say 3.4cm:15.5 you wouldn't be able to use that method. Yeah so the answer is 35.65 which rounds up to →35.7← because the second decimal place is five
