Answer:
2 cm = 50 km
Find what the rate would be if 2 became 10 by dividing
10/2=5
multiply the 5 with the rate
5 x 50 = 250
250 km apart
hope this helps
Step-by-step explanation:
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:

The given line is:

So we have:

We find 

So, a line perpendicular to the one given is of the form:

We substitute the given point to find "b":

Finally we have:

In point-slope form we have:
