Calculations I used:
t1=s/v1
t2=s/v2
Substract:
t1-t2=dt=s/v1-s/v2=(s*v2-s*v1)/(v1*v2)=s*(v2-v1)/(v1*v2)=s*dv/(v1*v2)
Therefore
s=(dt*v1*v2)/dv
I evaluated (v1*v2)/dv and it came to be 13.6 billion. Can someone verify it's correct? 172.68.51.112 13:08, 1 August 2018 (UTC)

- Do you mean 7.9 billion to convert to miles or to kilometers? Because my 13.6 bilion is to kilometers.
