152112 miles/h/megaparsec = 0.152112 mile/h/parsec= 3.063117 E-15 mile/h/mile.

Explanation:

As of now, the rate is the Hubble constant

#H_o#= 68 km/s/megaparsec

= 152112 miles/h/megaparsec

= 0.152112 mile/h/parsec

= 7.374591 E-07 miles/h/AU

= 3.063117 E-15 mile/h/mile.

I have used 1 parsec = 206265 AU, 1 AU = 149597871 km and i mile = 1.609344 km.
