Answer:
10 km
Step-by-step explanation:
For this problem, set up a ratio- you know that 6cm = 15km, and need how many km are represented by 4cm. Cross multiply so that you get 6/15 = 4/x, then 60 = 6x, and x (the value you are trying to solve for ) is equal to 10, or 10 km.
Hopefully this helps- let me know if you have any other questions!
[tex] \frac{6cm}{15km} = \frac{4cm}{x \: km} [/tex]
[tex]6x = 60[/tex]
[tex]x = 10[/tex]
the actual number of kilometers is 10 kilometers
