I am not sure, but it might help you
By def. of the derivative, we have for y = ln(x),



Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as


Recall that the constant e is defined by the limit,

Then in our limit, we end up with

In Mathematica, use
D[Log[x], x]
1mile=1.6 kilometer
26.2miles=26.2*1.6=41.92 kilometers
