Let’s dig deep further to understand the logic behind.

Total distance of going to moon and back as we discussed earlier is around 477,700 miles.
Now if you divide, 477,710 by 7300, you will get 65.4 years time to do a return journey to moon and back again.

Which is very much close to the average human life expectancy on earth. And if you are a male, you should be happy as you would still have around 2 years to live happily with your partner. Lol.
