You have a map of an area in France. The scale used is 2cm:8km. You want to ride to a national park. The park is shown on the map as 16 cm away.

64 km

Step-by-step explanation:

The ratio of map distance to actual distance is given by the scale. So, we can write the proportion ...

distance to park / distance on map = (8 km) / (2 cm)

distance to park = (distance on map) * (8 km) / (2 cm)

= (16 cm) * (8 km) / (2 cm)

= 64 km

The distance on the map represents a distance of 64 km to the park.
