Question

The scale of a map says that 2 cm represents 8 km. What is the actual number of kilometers that is represented by 3 centimeters on the map?​

Answer 1

The answer would be 12.

Explanation:

I got 12 using the information we were given. Seeing as 8km is represented by 2cm, 1 cm would be 4km, right? (8 divided by 2 is 4.) So using that, we just need to multiply 4 by 3 to find what the 3km would be on the map.

Answer 2

12kilometers
If 2cm=8km, 1cm=4km
Multiply both by three and you get that 3cm=12km
