Answer:

Using the Fibonacci sequence as a rough approximation:
#100 = 89 + 8 + 3# so sum #55 + 5 + 2 = 62#

Explanation:

The ratio between miles and kilometres is close to the limiting ratio between successive terms of the Fibonacci sequence.

#1,1,2,3,5,8,13,21,34,55,89,...#

So #5# miles is about #8# kilometres, #21# kilometres is about #13# miles, etc.
