HELLO
Rodger my good friend walked 1200 meters.
Kilo- 1000m
The two do not save money at the same rate, because if you make common denominators of 20, Anna saves 6 dollars for every 20, while Patrick only saves 5 dollars for every twenty earned. So, Anna ends up saving more than Patrick.

The answer is x=-1
Hope this helps:)
