If you're asking what the RBC lifespan is, it's 90-120 days.
If you're asking how long it takes to go through the body and come back to the same place, that's impossible to answer because it might take a short route (like through the coronary arteries and back) or a long route (to the tips of the toes and back) in order to end up where it started; it may also never end up exactly where it started.

It's 60 seconds. The blood in your body is fully circulated through the heart at about an average of a minute.

If it takes the long way to get back to it's original starting place, about one minute.
