This year alone we have conflicting speeds for the Hubble Constant with 67.66 (+ or - 0.42) from the Planck Mission and 73.45 (+ or - 1.66) from the Hubble Space Telescope.
The answer is simply found, and is between those figures.
The furthest thing we can see (in theory) is 13.8 billion light years away, the Universe being that old.
Divide 13.8 billion light years into one million megaparsec sections, as that is how the Hubble Constant is measured and you get 13.8 billion divided by 3.26 million equals just over 4,233.
The speed of light in kms is 298,051 kms/sec which is the apparent speed of expansion at 13.8 billion light years from us. Divide that by 4,233 and you get a Hubble Constant of 70.409 kms/sec for expansion.
