75/16 or 4 11/16 miles

Explanation:

Using the equation, D = rt where D is distance, r is rate, and t is time.

D = (2 1/2)(3 1/8)
Rewrite fractions from mixed fractions to improper:

D = (3/2)(25/8)
Multiply straight across:

D = 75/16
Convert to mixed fraction if you want, 16 goes into 75 4 times with a remainder of 11 so:
D = 4 11/16
