Answer:
32 km
Step-by-step explanation:
The scale for a map determines the ratio between the distance on the map and the distance in real like.
[tex]\frac{On Map}{Real World} =\frac{4cm}{8kilometers}[/tex]
Because we know the closest beach is 12 cm away then we have
[tex]\frac{4cm}{8 kilometers} =\frac{12cm}{?}[/tex].
Notice that 4cm becomes 12 cm by multiplying by 3. Do the same for the denominator and we'll have the distance in kilometers.
[tex]\frac{4 * 3cm}{8*4kilometers} =\frac{12 cm}{32 kilometers}[/tex]
