I have no idea what the total should be. What you have so far is

d = 2 1/2 miles + 5/8 miles + 3/8 miles

d = 5/2 + 5/8 + 3/8

The common denominator is 8.

To change 5/2 to something over 8, you have to multiply top and bottom of 5/2 by 4

5*4/2*4 = 20 / 8

d = 20/8 + 5/8 + 3/8

d = 28 / 8

d = 3 4/8

d = 3 1/2 miles
