Let x be the number of miles.
Then we convert the facts of the problem into algebra and get:
21.95 + .19x = 18.95 + .21x
Let us multiply everything by 100 to get rid of decimals...
2195 + 19x = 1895 + 21x
Now subtract 19 x from both sides
2195 = 1895 + 2x
Now subtract 1895 from both sides and then divide by two...
300 = 2x
x = 150 miles
