Answer:

<h2>200 miles</h2>

Step-by-step explanation:

$C(m)=0.50m+30\\\\\text{Put}\ C(m)=130\ \text{and solve the equation for }\ m:\\\\130=0.50m+30\qquad\text{subtract 30 from both sides}\\\\130-30=0.50m+30-30\\\\100=0.50m\qquad\text{multiply both sides by 2}\\\\(2)(100)=(2)(0.50m)\\\\200=1m\to m=200$
