Let's assume

total miles is x

case-1:

initial fee is $ 65

additional rate is $0.20 per mile

so, the total cost = initial fee + x* additional rate


C=65+0.20x

case-2:

initial fee is $ 0

additional rate is $0.70 per mile

so, the total cost = initial fee + x* additional rate


C=0+0.70x

Since, both costs are same

so, we can set them equal

and we get


65+0.20x=0+0.70x

now, we can solve for x


65=0.70x-0.20


65=0.50x


x=130

so, it would take 130 miles to drive for the two plans to cost the same .......Answer
