Question

Noella is checking your mouth for the distance to a beach the scale of the map is 4 cm represent 8 km if she finds the closest beach to be 12 from where she is how far away is the beach in kilometers

Answer 1

32 km

Explanation:

The scale for a map determines the ratio between the distance on the map and the distance in real like.

`(On Map)/(Real World) =(4cm)/(8kilometers)`

Because we know the closest beach is 12 cm away then we have

`(4cm)/(8 kilometers) =(12cm)/(?)`.

Notice that 4cm becomes 12 cm by multiplying by 3. Do the same for the denominator and we'll have the distance in kilometers.

`(4 * 3cm)/(8*4kilometers) =(12 cm)/(32 kilometers)`
