Let x be the number of miles after the first (so the number of miles traveled will be x+1).

The cost for the first mile is $4.20; the cost of each of the x additional miles is $2.50; the total cost was $49.20:

4.20%2B2.50x=49.20
2.50x=45.00
x=45%2F2.5+=+18

ANSWER: The number of miles traveled was x+1=19
