The scale of a map says that 4 cm represents 5 km. What is the actual number of kilometers that is represented by 5 centimeters on the map? Write in decimal form.

Answer 1

When using a map you read the scale in this case it is 4cm = 5km

Use this as a unit conversion factor. To identify it should be an equal statement. Also the unit your beginning with cm and the one you want km should be there.

Simply arrange the unit conversion as a fraction with unit you have at the bottom like below.

5 cm x 5 km = 25 km = 6.25 km

4 cm 4

The key to these problems is using right unit conversion factor and arrange it correctly so flipping it as needed. If you have any questions feel free to reach out I offer 1st free session.
