Reema has a road map with a scale of 1 cm representing 20 km. She drives 80 km on the road. What is the distance covered according to the map?

4 cm on map

Step-by-step explanation:

since 1 cm on map represents 20 km on road, we can either use proportion or ratio to solve this, I'm using direct proportion

  map : road

    1 : 20

    x : 80

20x = 80

    x = 80/20

    x =4

so 80 km on road is 4 cm on map
