Edwin's solution:

We must know that:

1km+=+1000m, with possible unit fractions %281km%29%2F%281000m%29,%281000m%29%2F%281km%29

1m+=+100cm, with possible unit fractions %281m%29%2F%28100cm%29,%28100cm%29%2F%281m%29

1cm+=+2.54in, with possible unit fractions %282.54cm%29%2F%281in%29,%282.54in%29%2F%281cm%29

12in+=+1ft, with possible unit fractions %2812in%29%2F%281ft%29,%281ft%29%2F%2812in%29

5280ft = 1mi, with possible unit fractions %285280ft%29%2F%281mi%29,%281mi%29%2F%285280ft%29

We start by putting 5km over 1:

%285km%29%2F1

Then we multiply by the unit fraction with km
in the denominator, so it will cancel with the km
in the numerator, so we now we have:

matrix%281%2C3%2C%285km%29%2F1%2C+%27%D7%27%2C+%281000m%29%2F%281km%29%29

so that the km's will cancel:

matrix%281%2C3%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000m%29%2F%281cross%28km%29%29%29

Then we multiply by the unit fraction with m
in the denominator, so it will cancel with the m
in the numerator, so now we have:

matrix%281%2C5%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000m%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cm%29%2F%281m%29+%29

and after canceling:


matrix%281%2C5%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cm%29%2F%281cross%28m%29%29+%29


Then we multiply by the unit fraction with cm
in the denominator, so it will cancel with the cm
in the numerator, so now we have:

matrix%281%2C7%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cm%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281in%29%2F%282.54cm%29+%29

and after cancelling:

matrix%281%2C7%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cross%28cm%29%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281in%29%2F%282.54cross%28cm%29%29+%29


Then we multiply by the unit fraction with in
in the denominator, so it will cancel with the in
in the numerator, so now we have:

matrix%281%2C9%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cross%28cm%29%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281in%29%2F%282.54cross%28cm%29%29%2C+%27%D7%27%2C+%281ft%29%2F%2812in%29+%29

and after canceling:

matrix%281%2C9%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cross%28cm%29%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281cross%28in%29%29%2F%282.54cross%28cm%29%29%2C+%27%D7%27%2C+%281ft%29%2F%2812cross%28in%29%29+%29

Then we multiply by the unit fraction with ft
in the denominator, so it will cancel with the ft
in the numerator, so now we have:

matrix%281%2C11%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cross%28cm%29%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281cross%28in%29%29%2F%282.54cross%28cm%29%29%2C+%27%D7%27%2C+%281ft%29%2F%2812cross%28in%29%29%2C+%27%D7%27%2C+%281mi%29%2F%285280ft%29+%29

and after canceling:

matrix%281%2C11%2C%285cross%28km%29%29%2F1%2C+%27%D7%27%2C+%281000cross%28m%29%29%2F%281cross%28km%29%29%2C+%27%D7%27%2C%28100cross%28cm%29%29%2F%281cross%28m%29%29%2C%27%D7%27%2C%281cross%28in%29%29%2F%282.54cross%28cm%29%29%2C+%27%D7%27%2C+%281cross%28ft%29%29%2F%2812cross%28in%29%29%2C+%27%D7%27%2C+%281mi%29%2F%285280cross%28ft%29%29+%29

Putting together everything that hasn't been canceled:

%28%285%29%281000%29%28100%29%28mi%29%29%2F%28%282.54%29%2812%29%285280%29%29

%28500000mi%29%2F160934.4

3.106855961mi

Or just a tiny bit over 3.1 miles.
