Alright, so first divide 20 km by 1.2 cm

16.6666666667

Multiply 16.6666666667 by 9

150

So it's 150 km!


Hope this helps!

[tex] \frac{1.2}{20} = \frac{9}{x} \\ [/tex]
Then you would cross mutiply and you would get
[tex]1.2x = 180[/tex]
Then you divide each side by 1.2
[tex](1.2x) \div 1.2 = (180) \div 1.2[/tex]
Then you solve and get
[tex]x = 150[/tex]
