Answer is 40km
Explanation:
So in this question we can use a proportion
Since
28km is 70% we can write it equal to 70%
28=70
and since 100% is unknown we can write it equal to x
100=x
Then we put it in proportion form
28/x=70/100
Then cross multiply and divide
28(100)/70=x
Which would equal 40
Answer: 
Step-by-step explanation:
Given a System of linear equations, the solution of the system is the point 
in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.
Having the following System of equations:
You can use the Elimination method to find the value of "x":
-Multiply the second equation by 3.
- Add the equations.
- Solve for "x".
Then, you get:
31/7 = 4 3/7.....3/7 is less then 1/2....so the closest integer is 4
