USING A REPRESENTATIVE FRACTION
"Do you see the red dots that show the locations of Brooklyn College and Columbus Circle? How many miles apart are the College and the Circle?"
"That's difficult!"
"Do it in two steps, Lou! First, figure out how many miles on the ground one inch on the map represents. (Don't forget, a scale of 1:182,932 means that one inch on the map represents 182,932 inches on the ground. And of course you know that there are 12 inches in a foot and 5280 feet in a mile! A couple of divisions are all that are needed!) Then, estimate how many inches separate the two places on the map! Et voila!! (NOTE: Screen and printout images may vary in size, so assume that the bar on the map labeled 'one inch' is, in fact, one inch!)"
4. The distance is:- miles.
Correct?:-

USING A BAR SCALE
"And to finish up, Lou, take a look at this map of the southwest corner of Central Park. It shows the place where the class meets for the field trip. It also shows you the location of a rock outcrop along a path in the park. How many feet does the class have to walk from its meeting place to the rock outcrop, assuming everyone sticks to the paths? How many meters?"
5. The distance is:- feet.
Correct?:-

6. The distance is:- meters.
