On a map of a city, the scale is 1 centimeter to 500 meters. if it is 4 kilometers between city hall and the library, how many centimeters is it on the map?

8 cm
125 cm
2,000 cm
80 cm

If you would like to know how many centimeters is it on the map, you can calculate this using the following steps:

1 cm ... 500 meters
x cm = ? ... 4 kilometers = 4000 meters

1 * 4000 = 500 * x
x = 1 * 4000 / 500
x = 8 cm

The correct result would be 8 cm.
