Terminal Velocity... about 120 MPH or 2 miles per minute

5.5 miles divided by 2 miles per minute equals 2.75 or 2 minutes, 45 seconds.

Given that it will a little time to accelerate to Vmax, try 3 minutes...

I'll watch from the ground... I was happy to have the static line...

NFE

PS: consider that all disclaimers to apply before attempting this jump...
I have jumped from 30,000 with a pull at 3000 canopy at 2500.

It is all fun except it is cold as a witches tit at 30,000.
