Please help. Astronomy question?
Assuming the universe began expanding when it came into existence and that it has always expanded at a constant rate, what would the age of the universe be if the Hubble constant was measured to be 62 km/s/Mpc?
Also answer has to be in billions of years. Thanks

Constant rate expansion disobeys all known laws of physics.
The Hubble constant works for visible univers, but has a bad flaw, Einstein proved that.

The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light, you know
Twelve million miles a minute, and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
'Cause there's bugger-all down here on Earth!

62 km/s/Mpc, better expressed as (to avoid ambiguity)
62 (km/s)/Mpc or 62 km/s•Mpc
1 pc = 3.09e13 km
1 Mpc = 3.09e19 km
62 km/s•Mpc x 1 Mpc / 3.09e19 km = 1.94e-18 km/km•s = 1.94e-18/s
inverting we get 5.15e17 s
or 1.63e10 yr
or 16.3 billion yr
