Answer:

64 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{2cm}{8kilometers}[/tex]

Because we know the park is 16 cm away then we have

[tex]\frac{2cm}{8 kilometers} =\frac{16cm}{?}[/tex].

Notice that 2cm becomes 16 cm by multiplying by 8. Do the same for the denominator and we'll have the distance in kilometers.

[tex]\frac{2 * 8cm}{8*8kilometers} =\frac{16 cm}{64 kilometers}[/tex]
