A map is a picture of a real life space that is obviously much smaller than real life. A whole city or state can be represented on a piece of paper. A scale map is drawn in such a way that it is proportional to the real space- it will have a legend that will tell you how much 1 cm corresponds to in miles, or km, or feet. Read the scale carefully to find the scale factor and units. You can set up a proportion using distances measured on the map to find out how far apart real life locations that are represented on the map are. Again, be extremely careful with units.
