20 miles the way you can get the answer is simply by dividing the number of miles by how many gallons you used so 402 divided by 201 is 2 now multiply 10 gallons by 2 and your answer is 20 hope it helps :)
So since he charges $1.85 for the first quarter mile we can keep that as it is for now. If we add 0.25 4 times to make it $1 that would be a mile. We just have to add $17.25 plus the original $1.85 fee
