The answer is, B 1cm=9.5 km
To solve this all you have to do is divide 47.5km by 5cm in order to get the answer of 1cm=9.5km.
The first step to solving this is to multiply both sides of the equation by 15.
9x - 5x = 15x - 15
Collect all of the like terms on the left side of the equals sign.
4x = 15x - 15
Move the variable to the left side of the equation and change its sign.
4x - 15x = -15
Now collect the like terms on the left side of the equation for the second time.
-11x = -15
Lastly,, divide both sides of the equation by -11 to get your final answer.

This means that the correct answer to your question is
