Amap drawn use a scale of 1cm/80 miles. two cities are 280 miles apart. how far apart are the cities on the map?

Map scales are supposed to be representative of what they portray, so when the scale of the map is 1cm/80 miles, that means that 1 cm measured on the map is equivalent to 80 miles in real life, and that 80 miles in real life will show up as 1 cm on the map.

So if two cities are 280 miles apart, that is (280/80) of 80 miles, which will be, on the map, (280/80) of 1 cm. So to get the distance on the map;

d = 1 x (280/80)
d = 3.5
So on the map, the cities are 3.5 cm apart

Hope this helped
