Are you serious? It's simple addition.. Find a factor of 3,4, and 5. 60. Multiply the tops and bottoms the the same number...
5 20/60 2 15/60 and 5 36/60= 13 11/60

This isn't statistics. It's just arithmetic.
5 1/3 + 2 1/4 + 5 3/5 =
5 + 1/3 + 2 + 1/4 + 5 + 3/5 =
5 + 2 + 5 + 1/3 + 1/4 + 3/5 =
12 + 20/60 + 15/60 + 36/60 =
12 + 71/60 = 13 + 11/60 =
13 11/60 or 13.183 miles

common denominator
5 20/60 + 2 15/60 + 5 36/60 = 12 71/60
or 13 11/60 of a mile

1/3=20/60
1/4=15/60
3/5=36/60
71/60=1 11/60+12=13 and 11/60
