Given:
The scale of a map is .
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
It means, 80 miles in real life = on the map.
1 mile in real life = on the map.
60 mile in real life = on the map.
= on the map.
= on the map.
Therefore, the buildings are apart on the map.
